The article is devoted to the usage of optical switches in ship's automated systems to increase the noise immunity of transmitted information. Ship’s sizes enlargement leads to the lengthening of communication lines. This causes the increasement of noises and electromagnetic interference to the signals in cable lines. Traditional methods of interference protection are becoming ineffective. Therefore, fiber-optic communication lines (FOCL) are used onboard the ships, where information is distributed in the form of modulated light pulses. Theoretically it makes possible to eliminate the interference at all. Also it increases the noise immunity of transmitted information in the main communication lines of ship’s systems. However, other sections of ship communications remain wired and are still subjected to interference. The usage of FOCL in all sections of ship communication lines is still impossible due to the high cost of optoelectronic switching equipment, where the principle of double conversion is used.

The purpose of the study is to propose and substantiate technical solutions for inter-satellite and subscriber paths of loworbit communication networks. There is a prospect of commercial use of such networks; therefore, the current stage of low-orbit satellite communications development is characterized by an increase in efforts to put the projects into practice. As part of the study, solutions for inter-satellite paths (ISP) in low-orbit communication systems and solutions that increase the capacity of their subscriber paths are considered. It is noted that ISPs can be built on the basis of radio and optical bands equipment. In this regard, the advantages and disadvantages of each case are considered. The expediency of constructing subscriber paths based on radio band equipment and the preference of constructing ISP based on optical band equipment are substantiated. The relationship between the feasibility of increasing the capacity of subscriber paths and the capabilities of ISP in terms of reliability and bandwidth is established.

Underwater wireless communication technology plays a key role in the field of marine equipment technology. In this paper, we experimentally demonstrate an underwater optical–acoustic cooperative communication platform for an underwater wireless data transmission system. The system utilizes an underwater Remote-Operated Vehicle (ROV) as a carrier, equipped with LEDbased optical communication and acoustic communication modems. In particular, the system applies optical communication to transmit large-scale data and applies acoustic communication to provide acoustic-assisted signaling exchange before optical transmission and Automatic Repeat Request (ARQ) during optical transmission. By experimentally measuring the transmission distance under different water quality conditions, we found that the system can achieve a data rate of up to 5 Mb/s over a laboratory underwater channel of 7.6 m. By comparing the attenuation coefficients for the outdoor underwater environment with that in clear seawater, we estimate that the achievable link distance in clear seawater can reach 11 m with a data rate of 3.125 MB/s. The proposed system takes both implementation complexity and cost into consideration and also provides significant guidance for future real-time high-speed underwater optical–acoustic communications.

Optical wireless communications in outdoor scenarios are challenged by uncontrollable atmospheric conditions that impair the channel quality. In this paper, different optical camera communications (OCC) equipment are experimentally studied in the laboratory and the field, and a sub-pixel architecture is raised as a potential solution for outdoor wireless sensor networks (WSN) applications, considering its achievable data throughput, the spatial division of sources, and the ability of cameras to overcome the attenuation caused by different atmospheric conditions such as rain, turbulence and the presence of aerosols. Sub-pixel OCC shows particularly adequate capabilities for some of the WSN applications presented, also in terms of cost-effectiveness and scalability. The novel topology of sub-pixel projection of multiple transmitters over the receiver using small optical devices is presented as a solution using OCC that re-uses camera equipment for communication purposes on top of video-monitoring.

The current railway track circuit monitoring system is prone to disturbances that can result in accidents. Meanwhile, basic signaling equipment is slow and cannot achieve satisfactory real-time data acquisition speed. This study aims to solve the aforementioned problems by designing an online monitoring and management platform for railway signal infrastructure, which is based on the graphical programming language LabVIEW. Online monitoring and management of railways’ basic signaling equipment allow real-time collection and communication of various signal equipment data. These processes also enable signal processing, chart display, acousto-optic alarm, user authority management, data storage, data query analysis, and report printing. The test results show that the LabVIEW-based basic signaling equipment for monitoring and managing railway systems can transmit data correctly and steadily, thereby resulting in convenient and ideal operation.

Recent experiments with optical fibers have reached a remarkable development for optical communication spectroscopy as well as a medical technology. Hollow optical fibers are required for optical communications. The measurement of the transmission of light through fibers can provide information about the fiber quality and about the far-field energy which radiates from the fiber end. We used five flexible hollow fused quartz fibers to study laser beam propagation down the fiber axis. Five different refractive index fluids were prepared and inserted into the fiber core to measure the transmitted intensity as a function of core property. The plots of the normalized, relative transmitted intensity measured as a function of the beam insertion point show the dependence of the transmitted intensity as a function of fiber diameter and refractive index fluid.

The evolving needs of network carriers are changing the design of optical networks. In order to reduce cost, latency, and power consumption, electrical switches are being replaced with optical switching fabrics at the core of the networks. An example of such a network is an Agile All-Photonic Network (AAPN).
This thesis presents a novel device that was designed to operate as an optical switch within the context of an AAPN network. The device is a Reprogrammable Optical Phase Array (ROPA), and the design consists of applying multiple electric fields of different magnitudes across an electro-optic material in order to create a diffractive optical element. The configuration of the electric fields can change to modify the properties of the diffractive device.
Such a device has a wide range of potential applications, and two different ROPA designs are presented. Both designs are optimized to function as 1xN optical switches. The switches are wavelength tunable and have switching times on the order of microseconds. The ROPA devices consist of two parts: a bulk electro-optic crystal, and a high-voltage CMOS chip for the electrical control of the device. The design, simulation, fabrication and testing of both the electrical and optical components of the devices are presented.

AbstractAutomated precision assembly of e.g. optical systems requires development efforts in manifold domains, such as part feeding, handling, alignment, bonding and quality control. The use of systematic design procedure enables the rapid and complete development of new applications and use cases using existing equipment. Combined with modular equipment and subsystems, the use of a standardized design process significantly reduces development time and therefore costs. A generic methodology based on the functional decomposition of assembly task requirements and a coherent synthesis of functional process building blocks can be an answer to reduced process ramp-up time, more stable processes and enable concurrent engineering for novel tool and process development.

AbstractThe rapid development of 4G and multimedia services drives the exponential increase of the demand for transmission bandwidth. The OTN technology therefore emerges. In recent years, the number of OTN devices in backbone and core equipment rooms has increased sharply. However, due to factors such as equipment room planning, air conditioner, and power supply, new electrical racks cannot be installed in the same equipment room as original optical racks during OTN expansion of 80-wavelength systems. The remote deployment of OTN electrical racks has certain impact on OTN system indicators, OM/OD, and OTU optical-layer parameters. This document analyzes the factors that are affected by the remote deployment of OTN electrical racks, creates simulation models based on scenarios, and provides suggestions on the remote deployment design of OTN electrical racks.

Computer science and electronics have a very big incidence in several research areas; optics and photonics are not the exception. The utilization of computers, electronic systems, and devices has allowed the authors to develop several projects to control processes. A description of the computer tool called Laser Micro-Lithography (LML) to characterize materials is realized. The Reasoning Based on Cases (RBC) and its implementation in the software using Java are presented. In order to guarantee the lithography precision, a control system based on a microcontroller was developed and coupled to the mechanical system. An alternative of LML, considering the use of a Personal Digital Assistant (PDA), instead of a Personal Computer (PC) is described. In this case, C language is used for programming. RBC optimizes the materials characterization, recovering information of materials previously characterized. The communication between the PDA and the displacement table is achieved by means of a system based on a micro-controller DSPIC. The developed computers tool permits obtaining lithography with channels narrower than an optical fiber with minimum equipment. The development of irradiance meters based on electronic automation is shown; this section includes the basic theoretical concepts, the experimental device design and the experimental results. Future research trends are presented, and as a consequence of the developed work, perspectives of micro drilling and cutting are also analyzed.

Most major high-speed applications, such as communications, environmental monitoring, transportation, smart homes, industries and gadgets are enabled by recent photonic technology. Basic all-optical logic gates are used in the development of image sensors, ultra-fast optical devices, and positioning equipment in high-speed applications. Among different technologies proposed for all-optical implementation, Semiconductor Optical Amplifiers (SOA) have been widely adopted. They have attractive features such as wide gain bandwidth, low power consumption, compactness and strong non-linearity. SOA still has a limitation that its spontaneous emission noise restricts the performance. The semiconductor optical amplifiers with quantum dots exhibit higher saturation output power, lower current density threshold, wider gain bandwidth, and low noise figure than conventional SOA. Quantum Dot Semiconductor Optical Amplifiers (QDSOAs) also have limitations like large size, high power consumption and spontaneous emission of noise. Photonic Crystal (PhC) is an artificial material that is suitable to overcome all drawbacks of SOA and QDSOA due to its simple structure and compactness, high speed, low power consumption, and low loss. PhC-based structures allow propagation of light in a controlled manner with its periodic crystal arrangements having dissimilar diffraction index. PhCs are considered to be a suitable structure for designing all-optical devices with compactness. In this chapter, an all-optical XOR is designed. Initially, the XOR gate is designed and simulated by using the FDTD method. The proposed XOR logic is achieved without nano-resonators and then with nanoresonators to get enhanced performance metrics in the form of high contrast ratio. The contrast ratio is 260 dB for the XOR gate with a delay time of 0.19 ps. The proposed XOR logic gate has potential practical applications for high speed applications of telecommunication systems.

Since merging is one of the most difficult situations for automated driving, merging support provided by infrastructure is extremely helpful for automated vehicles on motorways. However, in the early stages of automated vehicle penetration, infrastructure-side equipment to support merging is limited. In the first half of this chapter, a method to support speed control for inflow vehicles is proposed for the case where there is one detection device on the main lanes and one transmission/detection device for the vehicles in the inflow lane. In the second half, the case equipped with an additional detector and transmitter downstream on each lane is dealt with. New accurate information about the merging vehicles concerned could be given to the speed controller in the infrastructure. The control should be recalculated and sent to the inflow vehicle that has already started. Each control problem is formulated in the optimal control theory and calculated numerically by a nonlinear programming algorithm. The computational experiment is performed in each realistic situation.

The Communications Research Laboratory is planning a laser optical communication project to establish the basic technology of optical communications in space. The most important part of the experiment is maintaining the laser link between the satellite and the ground station by means of on-board laser communication equipment. The satellite will be launched in the summer of 1993. In this study of optical communication in space, several experiments are planned. The first is the acquisition and tracking of the satellite by using the point-ahead technique, which is the key to keeping the laser link. The second experiment is to measure the propagation characteristics of the laser beam through the atmosphere and to measure the beam pattern of the on-board laser diode. The third experiment is the high-accuracy attitude determination of the satellite by a controlled, polarized laser beam. The fourth and primary goal of the study is the dual-link optical communication experiment. The ground station includes a transmitting telescope with a fine pointing mechanism, a main telescope for receiving the signal from the satellite, and optics to modulate the Ar laser located in the Coude room under the telescope. In this paper, we will present the specifications of the ground equipment and some preliminary results of experiments that used the ground station.

Infrared eye trackers are employed to achieve communication through gaze interaction, which is an important application of modern electro-optics and computer technology to the benefit of persons with disabilities who have major motor impairments, as well as for general use as a human-to-computer interaction device. By tracking eye movements of persons with severe motor disabilities, the individuals can interact with automated equipment through movements of their gaze. In addition to purely passive systems, which may only employ ambient lighting, more typical eye trackers employ active infrared eye-tracking techniques. However, questions have arisen with regard to the potential optical radiation hazards of using infrared eye trackers for the much-extended durations of 10 to 12 hours each day for a lifetime. Conventional eye trackers employed in the research setting would rarely be used for more than an hour. Several exposure guidelines exist today, but the question has arisen whether the chronic nature of exposure for such an infrared illuminator for assistive devices falls outside the assumed conditions of daily exposure. This technical report explores the basis of the current human exposure guidelines, their scientific basis and underlying assumptions in order to determine the direct applicability of these guidelines to this application. It is found that the most limiting exposure criterion is the infrared exposure limit to protect against delayed changes in the crystalline lens of the eye. The Technical Committee also examined some representative eye trackers and found that the day-long average exposure in these typical examples of current technology did not exceed that criterion.
