Abstract:
Modern-day computers rely on electrical signaling for the processing and storage of data, which is bandwidth-limited and power hungry. This fact has long been realized in the communications field, where optical signaling is the norm. However, exploiting optical signaling in computing will require new on-chip devices that work seamlessly in both electrical and optical domains, without the need for repeated electrical-to-optical conversion. Phase-change devices can, in principle, provide such dual electrical-optical operation, but assimilating both functionalities into a single device has so far proved elusive owing to conflicting requirements of size-limited electrical switching and diffraction-limited optical response. Here, we combine plasmonics, photonics, and electronics to deliver an integrated phase-change memory cell that can be electrically or optically switched between binary or multilevel states. Crucially, this device can also be simultaneously read out both optically and electrically, offering a new strategy for merging computing and communications technologies.

Abstract:
Tungsten oxide-based materials have drawn huge attention for their versatile uses to construct various energy storage devices. Particularly, their electrochromic devices and optically-changing devices are intensively studied in terms of energy-saving. Furthermore, based on close connections in the forms of device structure and working mechanisms between these two main applications, bifunctional devices of tungsten oxide-based materials with energy storage and optical change came into our view, and when solar cells are integrated, multifunctional devices are accessible. In this article, we have reviewed the latest developments of tungsten oxide-based nanostructured materials in various kinds of applications, and our focus falls on their energy-related uses, especially supercapacitors, lithium ion batteries, electrochromic devices, and their bifunctional and multifunctional devices. Additionally, other applications such as photochromic devices, sensors, and photocatalysts of tungsten oxide-based materials have also been mentioned. We hope this article can shed light on the related applications of tungsten oxide-based materials and inspire new possibilities for further uses.

Abstract:
As the computer industry grows, so will the requirements for data storage. Magnetic memory has been the most stable method in terms of capacity and recording/reading speed. However, we have reached the point where a substantial increase in the capacity cannot be produced without increasing the size of the system. When compact discs (CDs) were introduced in the 1980�s they revolutionized the concept of data storage. While the initial force behind compact discs could easily be said to be the music industry, once recordable and rewritable discs became available they quickly found more use in the computer industry as backup devices. Since their inception, the capacity requirements have far exceeded what is available on a compact disc, and they are now following the same path as magnetic memories. Following this trend, it could be assumed that digital versatile discs or digital video discs (DVDs) have a limited lifetime as a storage medium. In fact it has been noted (Higuchi et al., 1999) that the maximum capacity of digital video discs will be reached in 3 � 5 years. The question then is, what comes next? The efficiency of conventional optical data storage is extremely poor. For an optically thick recording medium, both CDs and DVDs use less than 0.01% of the total volume to store the information. Three-dimensional bit optical data storage endeavors to increase the efficiency by recording information in a volume that is greater than 90% of the total volume. The concept of three-dimensional bit optical data storage was first proposed by Parthenopoulos and Rentzepis in 1989, where they demonstrated that capacities far exceeding that of compact discs could be achieved. Three-dimensional bit optical data storage relies on creating a highly localised chemical or physical change within a recording medium, such that further layers can be recorded without causing interference. Ideally the chemical/physical change in the material should be reversible to enable erasable/rewritable data storage. In order to create a highly localised effect nonlinear excitation can be used; whereby the excitation is limited to a small region around the focal spot. Depending on the material and recording method there are several techniques for reading the information such as transmission imaging or reflection confocal microscopy. However, all the recording and reading methods require focusing to a deep position within a recording medium, such focusing encounters spherical aberration as a result of the difference in the refractive indices between the immersion and recording media. This thesis has concentrated on several areas to understand and develop the concept of three-dimensional bit optical data storage. The photorefractive effect in crystals has been studied for many years and is now widely used in optoelectronic devices. The use of photorefractive polymers is a relatively new and exciting development in optical data storage. Until now they have been used solely in the area of holographic data storage. The research in this thesis was conducted using photorefractive materials that were fabricated in two polymer matrices, poly(N-vinylcarbazole) (PVK) and poly(Methyl Methacrylate) (PMMA). The recording samples also consisted of the following compounds in various proportions, 2,5-dimethyl-4-(p-nirtophenylazo)anisole (DMNPAA), 2,4,7-trinitro-9-fluorenone (TNF) and N-ethylcarbazole (ECZ). In this project two-photon excitation was used as the recording mechanism to achieve erasable/rewritable data storage in a photorefractive polymer. As a result of two-photon excitation, the quadratic dependence of excitation on the incident intensity produces an excitation volume that is confined to the focal region in both the transverse and axial directions. Therefore, focusing the laser beam above or below its previous position provides a method by which layers of information can be recorded in the depth direction of a material, without causing interference from neighbouring layers. The feasibility of two-photon excitation in photorefractive polymers is demonstrated in this thesis. The quadratic relationship between excitation and incident light in two-photon excitation requires high photon density to ensure efficient excitation. The use of ultra-short pulsed lasers, while effective, is not a practical solution for an optical data storage system. This thesis demonstrates the ability to produce three-dimensional erasable/rewritable data storage in a photorefractive polymer using continuous wave illumination. Using this technology it has been possible to achieve a density of 88 Gbits/cm3, which corresponds to a capacity of 670 Gbytes on a compact disc sized recording medium. This is an increase of 1000 times the capacity of a CD and 130 times the capacity of current DVDs. While erasable optical data storage is an exciting prospect there are problems associated with the deterioration of the information. For long term information storage a permanent recording process would be more practical. It is demonstrated that there is a point after which further increases in the recording power result in the formation of a micro-cavity. While two-photon excitation is the recording method for erasable data storage, the increase in power results in an increase in ultra-violet absorption such that multi-photon excitation may occur. This thesis demonstrates the ability to record multi-layered arrays of micro-cavities. The change in refractive index associated with an erasable bit is less than 1%. As a result only phase sensitive reading methods (transmission imaging or differential interference contrast (DIC) microscopy) can be used to image a recorded bit. Both transmission and DIC imaging systems have poor axial resolution and therefore limit the density of the recording system, as well as being large optical systems. The introduction of a split or quadrant detector reduces the size of the optical reading system and is demonstrated to be sensitive enough to detect the phase changes of a recorded bit. However, the change in refractive index across a micro-cavity is large enough that reflection confocal microscopy can be used to detect a bit. It is demonstrated in this thesis that multi-layered micro-cavity arrays can be read using reflection confocal microscopy. Focusing of light to deep positions within an optical thick recording medium has the effect of increasing spherical aberration resulting from the refractive index mismatching between the immersion and recording media. The work in this thesis illustrates the effect of spherical aberration on the performance of both the recording and reading systems. The work conducted in this thesis shows the ability to record multi-layered erasable/rewritable information in a photorefractive polymer using pulsed and continuous wave two-photon excitation. It has also been demonstrated that through multi-photon excitation multi-layered micro-cavity arrays can be fabricated. It has also been illustrated that while spherical aberration deteriorates the performance of the recording and reading systems it is possible to achieve a density of greater than 88 Gbits/cm3.

Abstract:
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, February 1999.
Includes bibliographical references (leaves 106-116).
Three different types of optical fiber devices were investigated for this thesis: actively modelocked fiber lasers, optical fiber ring buffers, and passively mode-locked fiber lasers. Intra-cavity soliton compression was employed in an actively mode-locked fiber laser to reduce the pulse width by a factor of 4.4 below the pulse widths predicted by standard active mode-locking theory. Stability regions for these solitons were mapped out and compared to theoretical predictions. In the second device the dynamics of a 5 Gbit/sec packet of ONES and ZEROS loaded into a phase modulated optical fiber ring buffer were experimentally investigated. A new mode of operation was explored where the cavity length of the buffer was slightly detuned from the modulation frequency that was driving the phase modulator. An investigation into the conditions for successful loading and the storage behavior was performed. In addition, relaxation oscillations, which have affected the storage time of previous high-speed optical ring buffers, were nearly eliminated with a CW holding beam, and significantly enhanced storage times were obtained. Investigations of passively mode-locked fiber lasers included both soliton and stretched-pulse implementations. Two different versions using the soliton configuration were studied; in both cases a waveguide amplifier was used to provide gain, allowing short cavity lengths. A polarization additive-pulse mode- locked version generated 116-fs, 130 pJ solitons at a repetition rate of 130 MHz. Preliminary work was also completed on a second short cavity soliton laser with a semiconductor saturable absorber mirror as the mode-locking mechanism. Using the stretched-pulse cavity design, an environmentally-stable fiber laser was demonstrated to generate 1.8 nJ pulses that were compressible to sub-100 fs. 980-nm pumping requirements for this laser were only 200 mW. Lastly, the first observation and characterization of resonant sideband formation in stretched-pulse fiber lasers was completed. Experimental results were evaluated in conjunction with numerical simulations and a theoretical analysis.

Abstract:
Theoretical and experimental techniques are developed to study three common approaches to focus error signal generation for optical data storage applications. Specifically, the astigmatic, obstruction knife edge (a.k.a. shaded aperture), and critical angle prism systems are studied. These techniques are then applied to a new focus detection system, based on a lateral shearing interferometer, developed by this author. The sensitivity of a given optical system to the primary design point, alignment errors, aberrations and optical recording medium topology are presented. A new approach to constructing the focus error signal for the astigmatic and interferometric techniques is presented which greatly reduces the alignment sensitivity.

Abstract:
A technique is presented that utilizes an on-axis intensity measurement to detect the reflected light from a multiple CD-ROM surface. The thesis includes a computer simulation of the detected signal for scans of various structures and discusses finite size detector effects. A suitably sized detector passes 77% of the total light flux at the detector plane without affecting the depth discrimination property of the technique. Experimentally, a breadboard Height Readout System (HRS) could detect height differences on test relief structures. A signal to noise ratio was obtained that corresponds to a noise equivalent height sensitivity of 30 Angstroms. Therefore, the HRS could discriminate between five levels on the test structure. An addition to the new technique uses a phase plate to determine if the focused beam is going into or out of a pit. Thus, the storage capability per unit area on the disk surface can be increased.

Abstract:
Light can be coupled out of a waveguide to a focused point by a focusing grating coupler and has possible applications in optical data storage. The grating can be fabricated with either e-beam techniques or holographic techniques. Two design methods are demonstrated that model the focusing grating coupler with holographic optical elements. Both methods take a geometrical optics approach to designing the holographic optical elements and both methods make use of commercially available ray trace programs. The first method uses complicated non-rotationally symmetric construction optics and requires either a modified ray trace program or special user defined surfaces. The second method involves a much simpler approach which did not require any changes to an existing ray trace program and requires only rotationally symmetric elements to correct the aberrations.

Abstract:
AbstractOver the last 100 years, there has been an explosion of research in the field of animal bioacoustics. These changes have been facilitated by technological advances, decrease in size and cost of recording equipment, increased battery life and data storage capabilities, the transition from analog-to-digital recorders, and the development of sound analysis software. Acousticians can now study the airborne and underwater sounds from vocal species across the globe at temporal and spatial scales that were not previously feasible and often in the absence of human observers. Many advances in the field of bioacoustics were enabled by equipment initially developed for the military, professional musicians, and radio, TV, and film industries. This chapter reviews the history of the development of sound recorders, transducers (i.e., microphones and hydrophones), and signal processing hardware and software used in animal bioacoustics research. Microphones and hydrophones can be used as a single sensor or as an array of elements facilitating the localization of sound sources. Analog recorders, which relied on magnetic tape, have been replaced with digital recorders; acoustic data was initially stored on tapes, but is now stored on optical discs, hard drives, and/or solid-state memories. Recently, tablets and smartphones have become popular recording and analysis devices. With these advances, it has never been easier, or more cost-efficient, to study the sounds of the world.

Abstract:
AbstractReservoir computing is a novel computational framework based on the characteristic behavior of recurrent neural networks. In particular, a recurrent neural network for reservoir computing is defined as a reservoir, which is implemented as a fixed and nonlinear system. Recently, to overcome the limitation of data throughput between processors and storage devices in conventional computer systems during processing, known as the Von Neumann bottleneck, physical implementations of reservoirs have been actively investigated in various research fields. The author’s group has been currently studying a quantum dot reservoir, which consists of coupled structures of randomly dispersed quantum dots, as a physical reservoir. The quantum dot reservoir is driven by sequential signal inputs using radiation with laser pulses, and the characteristic dynamics of the excited energy in the network are exhibited with the corresponding spatiotemporal fluorescence outputs. We have presented the fundamental physics of a quantum dot reservoir. Subsequently, experimental methods have been introduced to prepare a practical quantum dot reservoir. Next, we have presented the experimental input/output properties of our quantum dot reservoir. Here, we experimentally focused on the relaxation of fluorescence outputs, which indicates the characteristics of optical energy dynamics in the reservoir, and qualitatively discussed the usability of quantum dot reservoirs based on their properties. Finally, we have presented experimental reservoir computing based on spatiotemporal fluorescence outputs from a quantum dot reservoir. We consider that the achievements of quantum dot reservoirs can be effectively utilized for advanced reservoir computing.

Abstract:
Presently, optical data storage systems are based on the use of near infrared GaAIAs diode lasers operating at wavelengths of 780 - 830 nm. Substantial advances of the areal storage density are possible by using lasers in the blue - green wavelength range. Such blue - green laser sources can be developed by making use of nonlinear optical processes for frequency upconversion of existing state-of-the-art III-V semiconductor lasers. These approaches circumvent the severe fundamental material fabrication problems associated with the potential development of blue semiconductor injection lasers.

Abstract:
For an optical head in compact disc (CD) system, an optical device called "laser coupler" (LC) has been developed and used in commercially sold players. This device integrates a laser diode, photo detectors and a micro-prism into one small chip.[1] Using integrated devices of this kind, we can make small, light and stable optical heads with less material and production costs. MiniDisc (MD) systems have become popular as a novel audio system. In this system, a 64mm-diameter disc in a cartridge can record and play back 74 min. of compressed audio data or store 140 MB of user data, using magneto-optical (MO) technology. To improve the portability of this MD systems, smaller, lighter and more stable optical heads are necessary. For this reason, several kinds of integrated optical devices, such as laminated prism [2], holographic optical element (HOE) [3,4], have been reported. In this paper we present a new integrated optical device which we call MiniDisc laser coupler (MD-LC). The simple construction of this device allows an easy mass-production.

Abstract:
To obtain a small and reliable optical pick-up capable of being mass-produced, it is important to integrate optical components in a small packaged device. Recently several authors reported hybrid integrated optical pick-up devices, using a micro-prism and holograms [1]. However there are few reports of monolithic optical pick-ups [2]. Based on the novel optical device previously reported [3], and we fabricated a monolithic optical pick-up in combination with a plastic lens and an actuator.

Abstract:
The data pattern on the recording surface can be thought of as collections of cosinusoidal gratings, no matter what the technique used for modulating the reflected light. Reflected light from a focused beam contains a zero order and ± 1st diffracted orders, as shown in Figure 1. The separation angle between the diffracted orders depends on the spatial frequency of the grating. High spatial frequencies yield large separation of the diffracted orders. Light collected by the objective lens contains the zero order and portions of the diffracted orders. The signal amplitude received from the detectors depends on the modulation of the interference between the diffracted orders and the zero order. The amount of modulation depends on the overlap area. At low frequencies, the overlap area is most of the collection aperture. At high frequencies the overlap area reduces, so the signal amplitude decreases.

Abstract:
A number of Optical Digital data storage devices were introduced in recent years. Most of these devices use a 12" diameter write-once-read-mostly (WORM) optical disk with a capacity around 1 GByte per disk side. These devices are aimed at the high end of data storage hierarchy, and larger capacity is also necessary to bring the cost per bit to a reasonable value when the cost of laser and optics are high at the early stage of development. Much progress has been made in the past two years. The success of laser diode based compact audio disk players in the market place has changed this situation dramatically. It is now economically feasible to produce optical digital recording devices with a formfactor of a 5 1/4" Winchester drive, using a 130 mm diameter WORM disk, to store 200 MByte/side, and compete favorably with existing magnetic recording devices on a cost per bit basis.
