Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive contributed volume that aims to describe and explain the design, fabrication, operating characteristics, and specific applications of the most popular and useful types of specialty optical fibers. These “specialty fibers include any kind of optical fiber that has been architecturally manipulated to diverge from a conventional structure. For instance, metal-coated fibers can be utilized for bandwidth improvement, and hollow core fibers offer more controllable dispersion for sensitive medical procedures. Applications for these specialty fibers abound in the biomedical, sensors, and industrial fields, as well as in more traditional communications capacities. This book will act as a specialty fiber “guided tour, hosted by the top names in the discipline. The globally renowned editors, Drs. Mendez and Morse, have extensive experience in research, academia, and industry. *Completely covers biomedical and industrial sensor technology with emphasis on real world applications *Comparative studies of pros and cons of all fiber types with relation to test and measurement, mechanical properties and strength, and reliability *Easy to access essential facts and details at the begining of each chapter

Download or read book Photonic Crystal Enhanced Electrooptic Polymer Based Optical Modulators for Realization of Integrated 40 GS s All Optical Analog Digital Converters with 8 Effective Number of Bits written by Kai Wei and published by . This book was released on 2021 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-speed, broadband, and compact analog-to-digital converters (ADC) are the key components in signal waveform generation and efficient detection for future telecommunication and remote sensing applications. Canonical electronic ADCs suffers from limited effective number of bits (ENOB) at giga-sampling rate due to electronic clock aperture jitter and comparator ambiguity due to the transistor bandwidth limitations. An electrically interleaved ADC operating at lower sampling rates or a hybrid ADC using optically sampled and electrically quantized structures that leverages the low optical aperture jitter of mode-locked laser and high-resolution electronic quantization are not only power consuming but are also limited in effective sampling rate within 10 GS/s as the quantizer outputs still must be accurately aligned in time to form the input information in electronic domain. On the other hand, the reported all-optical ADC (AOADC) benefits from the low jitter of optical clock, while quantizes the input signal in optical domain using spatial modulation. In this dissertation, various design innovations leading to paths of a fully integrated 40 GS/s AOADC with 8 ENOB by incorporating integrated stable clock using self-forced optical phase modulator (PM) based opto-electronic oscillators (OEO) and single-channel spatial light modulator (SLM) by advancing research innovations of the past laboratory graduates.Design of optical PM and SLM designs are based on broadband traveling-wave coupled microstrip (CMS) electrode structures with improved phase and angular deflection modulation using slow-waveguiding behavior of 1-D photonic crystal (PhC) topologies as superstrate using optical beam propagation (OptiBPM), finite-difference-time-domain (OptiFDTD), and finite element method (HFSS). Optimized design geometries of 1-D PhC over 1550 nm is considered to minimize the optical loss while the modulation sensitivity is enhanced by about 108% compared to modulator designs without the PhC layer. Similar spatial modulation sensitivity improvements are achieved for SLMs with leaky wave designs. These designs are implemented on low-cost Si-photonics and electro-optic (E-O) chromophores on low loss and higher index PMMI host material rather than standard PMMA. Novel design of OEO based on PM rather than Mach-Zehnder modulator (MZM) has advantage of bias voltage independence that makes OEO less sensitive to shift in bias voltage due to piezo-electric or pyro-electric properties of E-O material, but then requires phase to intensity modulators (PM-IM). Sagnac-loop based OEO is demonstrated, where close-in to carrier phase noise at 10 GHz are reduced using self-forced techniques of self-injection locking and dual self-phase-locked loop (SILDPLL) for long-term stability of optical clocks to predict timing jitter as low as 19.5 fs using 3-/5-km fiber mandrills in modular experiment.To achieve a monolithically integrated AOADC consisting of the proposed SLM and stable optical clock provided by OEOs with the estimated performance, a heterogeneously integrated InP multi-mode laser (MML) as an on-chip OEO source, where inter-modal oscillation and PM-IM convertor rather than relying on Sagnac-loop design, where a non-reciprocal phase shifter (NRPS) is not compatible with Si on-chip integration at the present. RF signal generated from MML typically suffers poor stabilization and 25-fold reduction in timing jitter is measured compared to the free-running case, when SEILDPLL with external optical delays of 5-/15-(mu)s are employed. Moreover, for a fully integrated design rather than modular fiber mandrills, both non-dispersive and dispersive add-drop filter (ADF) resonators are modeled using both full-wave OptiFDTD and proven MATLAB codes on SiN based optical time delays of 975 ns within a chip area of 27 cm2 and 0.1 cm2, respectively. Furthermore, limits of performance improvements using a combined stabilization processes of self-mode-locking (SML) techniques and self-forced SML are investigated. Timing jitter of a 13-mode SML (e.g., fabricated using HHI foundry service) with 700 ns SEIL and 700-/900-ns DSPLL integrated IOEO is estimated to be only 7.6 fs at 10 GHz.

Book excerpt: To improve the Spur Free Dynamic Range of analog electro-optic modulators in the>10 GHz regime, techniques for improving the linearity of these devices must be developed. This report discusses an investigation into electro-optic directional couplers that use variable coupling in polymer-based waveguide structures. The approach begins with determining the desired response function, in this case a trapezoid. The Fourier transform method is then applied to synthesize the variable coupling function which results in the desired output response. This initial coupling function is iteratively modified using Newton's method to obtain a coupling design that can be implemented in a polymer waveguide. Approaches to achieving the variable coupling, including regions of negative coupling, are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Optoelectronics will undoubtedly playamajor role in the applied sciences of the next century. This is due to the fact that optoelectronics holds the key to future communication developments which require high data transmission rates and of a extremely large bandwidths. For example, an optical fiber having a diameter few micrometers has a bandwidth of 50 THz, where an impressive number of channels having high bit data rates can be simultaneously propagated. At present, optical data streams of 100 Gb/s are being tested for use in the near future. Optoelectronics has advanced considerably in the last few years. This is due to the fact that major developments in the area of semiconductors, such as hetero structures based on III-V compounds or mesoscopic structures at the nanometer scale such as quantum weHs, quantum wires and quantum dots, have found robust applications in the generation, modulation, detection and processing of light. Major developments in glass techniques have also dramaticaHy improved the performance of optoelectronic devices based on optical fibers. The optical fiber doped with rare-earth materials has aHowed the amplification of propagating light, compensating its own los ses and even generating coherent light in fiber lasers. The UV irradiation of fibers has been used to inscribe gratings of hundreds of nanometer size inside the fiber, generating a large class of devices used for modulation, wavelength selection and other applications.
