Book excerpt: Future growth of optical communication into new application and market space is highly dependent on the ability of optical receivers to increase functionality while reducing price and physical size. Current hybrid receiver technology is inadequate in meeting the cost and performance demands of future market. Monolithic integration and new material systems are potential solutions and have been the focus of research investigation. This thesis summarizes the research progress of monolithic integration on InP, and the achievements in realizing 1.55[micro]m photodetector on GaAs and Si and their potentials for monolithic opto-electronic integrated circuits. The overall trend for next generation receivers is to move towards higher levels of integration, with investigation in new material systems that have the potentials for lower cost and larger scale integration. The impact of monolithic integration optical receiver components is analyzed in a cost analysis model.

This book was released on 2007-11-24 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical networks have been in commercial deployment since the early 1980s as a result of advances in optical, photonic, and material technologies. Although the initial deployment was based on silica ?ber with a single wavelength modulated at low data rates, it was quickly demonstrated that ?ber can deliver much more bandwidth than any other transmission medium, twisted pair wire, coaxial cable, or wireless. Since then, the optical network evolved to include more exciting technologies, gratings, optical ?lters, optical multiplexers, and optical ampli?ers so that today a single ?ber can transport an unprecedented aggregate data rate that exceeds Tbps, and this is not the upper limit yet. Thus, the ?ber optic network has been the network of choice, and it is expected to remain so for many generationsto come, for both synchronousand asynchronouspayloads; voice, data, video, interactive video, games, music, text, and more. In the last few years, we have also witnessed an increase in network attacks as a result of store andforwardcomputer-basednodes. These attackshave manymaliciousobjectives:harvestsomeone else’s data, impersonate another user, cause denial of service, destroy ?les, and more. As a result, a new ?eld in communicationis becomingimportant,communicationnetworksand informationse- rity. In fact, the network architect and system designer is currently challenged to include enhanced features such as intruder detection, service restoration and countermeasures, intruder avoidance, and so on. In all, the next generation optical network is intelligent and able to detect and outsmart malicious intruders.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The last decade has seen an exponential increase in the magnitude and consumption of digital information. Online video streaming, cloud storage, the growing number of devices connected to the web via the "Internet of Things", and artificial intelligence, are emerging applications that require low-latency, high-speed networks. With optical carrier frequencies operating at 100s of THz for common communication wavelengths and optical fibers having both high bandwidth and low attenuation, optical communications in data centers is imminent. However, the bottleneck lies at the interface between optics and electronics, where information is converted from one domain to the other. This work explores historical and recent advances in improving the hardware bottleneck through "electro-photonic integration": the dense or monolithic integration of electronic and photonic devices onto a single semiconductor die. Unlike digital circuits, where silicon is the obvious choice, the implementation of high-speed electronic and photonic hardware can be enabled by various semiconductors including silicon, silicon germanium, gallium arsenide, and indium phosphide. A comparison of these semiconductors is presented to assess their current fit for meeting future data rate demands. Within the topic of electro-photonic integration, high-speed photodetectors are experimentally characterized and assembled with an electronic receiver. The knowledge gained from this process is then used to formulate a top-down, electro-photonic receiver design approach. The methodology incorporates three main blocks: the photodetector, electro-photonic assembly environment, and a simple, technology-based model of the transimpedance amplifier. This approach combines the otherwise separate photonic and electronic design processes in a simple, complete manner, allowing component vendors to consider co-designing or monolithically integrating devices with a technology platform that best fits customer requirements.

Available in PDF, EPUB and Kindle. Book excerpt: Optical networks are leaving the labs and becoming a reality. Despite the current crisis of the telecom industry, our everyday life increasingly depends on communication networks for information exchange, medicine, education, data transfer, commerce, and many other endeavours. High capacity links are required by the large futemet traffic demand, and optical networks remain one of the most promising technologies for meeting these needs. WDM systems are today widely deployed, thanks to low-cost at extreme data rates and high reliability of optical components, such as optical amplifiers and fixed/tunable filters and transceivers. Access and metropolitan area networks are increasingly based on optical technologies to overcome the electronic bottleneck at the network edge. Traditional multi-layer architectures, such as the widely deployed IP/ATM/SDH protocol stack, are increasingly based on WDM transport; further efforts are sought to move at the optical layer more of the functionalities available today in higher protocol layers. New components and subsystems for very high speed optical networks offer new design opportunities to network operators and designers. The trends towards dynamically configurable all-optical network infrastructures open up a wide range of new network engineering and design choices, which must face issues such as interoperability and unified control and management.

This book was released on 2008-07-16 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fibre-to-the-Home networks constitute a fundamental telecom segment with the required potential to match the huge capacity of transport networks with the new user communication demands. Huge investments in access network infrastructure are expected for the next decade, with many initiatives already launched around the globe recently, driven by the new broadband service demands and the necessity by operators to deploy a future-proof infrastructure in the field. Dense FTTH Passive Optical Networks (PONs) is a cost-efficient way to build fibre access, and international standards (G/E-PON) have been already launched, leading to new set of telecom products for mass deployment. However, these systems only make use of less than 1% of the optical bandwidth; thus, relevant research is taking place to maximize the capacity of these systems, with the latest opto-electronic technologies, demonstrating that the huge bandwidth available through the fibre access can be exploited in a cost-efficient and reliable manner. Next-Generation FTTH Passive Optical Networks gathers and analyzes the most relevant techniques developed recently on technologies for the next generation FTTH networks, trying to answer the question: what’s after G/E-PONs?

Download or read book DYNAMIC DAMPING IN OPTICAL RECEIVERS written by Pouria Aminfar and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's telecommunications involves ever-increasing amounts of optical communication. Besides being an important component of the long-haul network, optical communications are also being used in data centers, circuit boards, integrated circuits, and the next generation of mobile networks. This thesis proposes an optical receiver in which the damping factor of both the transimpedance and post amplifiers is modulated synchronously with incoming data. Modulation of the damping factor allows the fast response of the low-damping factor while mitigating the intersymbol interference (ISI) associated with underdamped systems. To investigate the modulated damping shunt-feedback transimpedance amplifier (SF-TIA), some methods, including switching the feedback resistor and modulating the damping factor by a sine wave, are used. Due to damping factor value limitation by changing the shunt-feedback and complexity of producing appropriate value of the sine wave with proper DC offset, amplitude and phase, damping factor modulation by a rail-to-rail square wave signal is presented where only phase adjustment is necessary and has better noise performance, Vertical Eye Opening (VEO) gain and gain to power ratio. The extension of dynamic damping to the post amplifier is investigated through simulation at 10 Gb/s. A shunt-feedback TIA with cross-coupled inverters at the output, optimized to reach minimum input-referred noise is used as a reference for creating SF-TIA and Cherry-Hooper post-amplifier (CH-PA) blocks. By modulating the damping factor in both blocks, the proposed system achieves more than three times the VEO and lower input-referred noise compared to the optimized reference. Alternatively, an equal-gain modulated system has 40 % lower power consumption compared to the reference design.
