Повний текст джерелаIn this work, we develop a novel polarized nonlinear microscopy method that exploits sub-diffraction resolution information. Fourier analysis of the polarization modulated nonlinear signal is performed on over-sampled, drift-corrected images (50nm pixel size). The information gained by polarization-induced modulation signals provides a higher level of spatial selectivity that is directly related to the local optical response of the investigated system, at a scale below the diffraction limit. The gain in spatial scale is due to the additional spatial sensitivity brought by polarization. This approach is applied to polarized second harmonic generation imaging in plasmonic nanostructures (150nm size) of multi-branched shapes, in which the vectorial nature of the local field confinement can be retrieved with a resolution of 40 nm. We also demonstrate the possibility to image spatial heterogeneities within crystalline ferroelectric BaTiO3 nanoparticles of 70nm to 500nm size, emphasizing in particular the existence of a centrosymmetric shell in small size structures. These nanostructures will be used as starting models for coherent optical probes in biological media (cells, tissue slices or in vivo) with two objectives. First, the nonlinear nature of their emission will make them stable and tunable nanosources, able to report their localization with high accuracy in 3D, potentially sensing local environment changes, and actively inducing perturbations such as controlled temperature increase at the nanoscale. Second, the coherent nature of their emission will make them useful as local nanoprobes for wavefront and polarization correction through scattering media

Повний текст джерелаWith the exponential growth of the embedded systems and the so-called IoT objects, the need of reducing power consumption for environmental and economic considerations requires better power-saving techniques without compromising circuit performances. However, CMOS transistors are achieving their physical limits in terms of scaling and the opportunities to enhance the integrated circuit will be more on the design side than on the technology side. Thereto, it is noticeable that complex digital circuits spent a significant amount of energy during idle periods and tend to activate much more blocks than needed. This drawback results from the usage of the synchronous paradigm. Asynchronous circuits provide intrinsic and local signals that mitigate the unnecessary block activation in circuits and offers an intrinsic idle mode. Moreover, these signals are usable to locally manage body-bias voltages in Fully Depleted Silicon On Insulator (FD-SOI) in order to save power. This thesis proposes a design strategy dedicated to asynchronous circuits exploiting the body-biasing facilities of the FD-SOI technology. Firstly, an analysis of the FD-SOI technology has been made in order to analyze the new degrees of freedom offered to the designers by mainly controlling the transistor threshold voltage (Vth) thanks to body-biasing effect. This latter is indeed able to change the transistor speed and power consumption. Secondly, a body-biasing standard cell based on a level shifter architecture has been designed in order to locally adapt the body-biasing voltage. Thirdly, we proposed a distributed activity-driven strategy easily managing a large number of Body-Biasing Domains (BBDs). Lastly, the aforementioned techniques have been implemented and tested in a chip designed in 28 nm FD-SOI technology from STMicroelectronics

Повний текст джерелаIn the competition of the miniaturization of integrated electronic circuits, UTBB-FDSOI technologies are better adapted to nanometric sizes, because they can limit the problems due to the random doping variations used in conventional “bulk” transistors and bring a significant improvement in terms of performance and low power design. This thesis is a contribution to the development of novel building blocks for PLL using complementary logic in 28nm UTBB-FDSOI technology. Using this technology, we proposed a complementary inverter based on a pair of back-gate cross-coupled inverters offering a fully symmetrical operation of complementary signals. This design concept can be extended to any digital cells to generate more stable, symmetrical and resilient output signals. First, we designed a fast and efficient ring oscillator composed by four complementary inverters delivering quadrature clocks which oscillation frequency is 7.3GHz. Then using complementary logic and back-gate control structure, we proposed an efficient solution to produce novel structures of VRCO, PFD, Charge pump, divisor etc., which are the key building blocks of high-speed low noise PLLs. All these designs have been simulated and verified using Cadence. Moreover, a test chip of RO, current mirror and VCRO have already been realized in silicon and tested

Повний текст джерелаThe hybrid integration of individual photonic elements appears as promising, because it may provide high performances, propose new optical functionalities and products and exploit new propagation modes of light beams. This approach requires an accurate multi Degree-Of-Freedom (DOF) positioning of the individual photonic elements. Hence, the inaccurate multi-DOF measurement and robots control are the main locks to overcome, notably at the micro-scale. For this sake, an original photo-robotic approach has been proposed, relying on multi-DOF robot motion associated with the use of 1-D Fabry-Perot interferometry measure to realize multi-DOF pose measure. This approach notably integrates the issue of 6-DOF robot calibration that has been studied through extrinsic and/or intrinsic geometric parameters calibration. In order to find the appropriate calibration strategy for high positioning accuracy and adapted to the context of micro-positioning of optical components, a quantification and durability analysis of optical and robotic performances have been investigated. Experimental investigations demonstrate that a rotational and translational positioning accuracy of 0.004° and 27.6 nm have been obtained respectively.This photo-robotic approach has especially been applied to achieve the 6-DOF positioning of an optical lamella relative to an optical fiber with high accuracy that also conduct to maximum optical performances. The approach has also been applied to control the optical polarization states at the output of an hybrid optical system through achieving high accurate rotations of a specific optical wave plate around the optical axis. The experimental results notably demonstrate that the high positioning accuracy enables to accurately control of the optical polarization state
Cao, Shuiyan. "Using plasmonic nanostructures to control electrically excited light emission." Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLS042/document.
Повний текст джерелаIn this thesis, we use different plasmonic nanostructures to control the emission of electrically-excited light. Our electrical emission is from an “STM-nanosource” which uses the inelastic tunnel current between the tip of a scanning tunneling microscope (STM) and a metallic sample, to locally excite both localized and propagating surface plasmon polaritons. The interaction of our STM-nanosource and a circular plasmonic lens (a series of concentric slits etched in a thick gold film) produces a radially polarized microsource of low angular spread (≈±4°). The influence of the structural parameters on the angular spread of the resulting microsource is also investigated. In addition, a low angular spread (<±7°) for a large wavelength range (650-850 nm) is achieved. Thus this electrically-driven microsource of nearly collimated light has a broad spectral response and is optimal over a wide energy range, especially in comparison with other resonant plasmonic structures such as Yagi-Uda nanoantennas. The interaction of our STM-nanosource and an elliptical plasmonic lens (a single elliptical slit etched in a thick gold film) is also studied. When the STM excitation is located at the focal point position of the elliptical plasmonic lens, a directional light beam of low angular spread is acquired. Moreover, in the experiment we find that by changing the eccentricity of the elliptical plasmonic lens, the emission angle is varied. It is found that the larger the eccentricity of the elliptical lens, the higher the emission angle. This study provides a better understanding of how plasmonic nanostructures shape the emission of light. The interaction of STM-excited SPPs and a planar plasmonic multi-layer stack structure is also investigated. It is demonstrated that using STM excitation we can probe the optical band structure of the Au-SiO₂-Au stack. We find that the thickness of the dielectric plays an important role in changing the coupling between the modes. We also compare the results obtained by both laser and STM excitation of the same stack structure. The results indicate that the STM technique is superior in sensitivity. These findings highlight the potential of the STM as a sensitive optical nanoscopic technique to probe the optical bands of plasmonic nanostructures. Finally, the interaction of an STM-nanosource and an individual triangular plate is also studied. We find that when the STM excitation is centered on the triangular plate, there is no directional light emission. However, when the STM-nanosource is located on the edge of the triangle, directional light emission is obtained. This study provides us a novel avenue to achieve directional light emission. We also study probing the optical LDOS of the triangle with the STM-nanosource. Thus, our results show that the manipulation of light is achieved through SPP-matter interactions. Using plasmonic nanostructures, we control the collimation, polarization, and direction of the light originating from the STM-nanosource
