Book excerpt: One of the Top Selling Physics Books according to YBP Library Services The exotic effects of slow light have been widely observed in the laboratory. However, current literature fails to explore the wider field of slow light in photonic structures and optical fibers. Reflecting recent research, Slow Light: Science and Applications presents a comprehensive introduction to slow light and its potential applications, including storage, switching, DOD applications, and nonlinear optics. The book covers fundamentals of slow light in various media, including atomic media, semiconductors, fibers, and photonic structures. Leading authorities in such diverse fields as atomic vapor spectroscopy, fiber amplifiers, and integrated optics provide an interdisciplinary perspective. They uncover potential applications in both linear and nonlinear optics. While it is impossible to account for all the captivating developments that have occurred in the last few years, this book provides an exceptional survey of the current state of the slow light field.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future optical switched wavelength division multiplexed (WDM) networks will require all optical wavelength conversion to avoid contention in a node when two signals on the same wavelength are being switched to the same output fiber. These future networks will also employ advanced modulation formats in order to increase the capacity of optical networks. In order to perform wavelength conversion operations on advanced modulation formats, a coherent nonlinear process, such as four-wave mixing (FWM), is required to preserve the amplitude and phase information. The phase noise transfer problem has crucial significance for the exploitation of FWM-based wavelength converters for advanced modulation formats because the phase noise transfer degrades the overall system performance. In this work, the required optical signal to noise ratio (OSNR) and laser phase noise (linewidth) limits are calculated via Monte Carlo simulations for the wavelength conversion of advanced modulation formats including DQPSK and M-QAM. Due to the sensitivity of M-QAM signals with respect to phase noise, the conversion performance is investigated using two different decision-directed phase-locked loop carrier phase recovery algorithms. In order to develop a validated numerical model for all-optical wavelength conversion of advanced modulation formats, the required OSNR versus pump linewidth at two values of bit error rate (BER) of 10-3 and 10-4 for DQPSK, 16-QAM and 64-QAM are reported for degenerate and non-degenerate FWM. With these calculations, the performance of wavelength conversion of advanced modulation formats will be guaranteed by selecting lasers with linewidths below these linewidth limits. As a next step of this work, All-optical wavelength conversion of Nyquist-WDM Superchannel using FWM in an SOA based on advanced modulation formats such as DQPSK, 16 and 64- QAM are demonstrated.

Book excerpt: Wavelength converters are essential building blocks of future all-optical wavelength-routed optical networks. Wavelength converters based on four-wave mixing in semiconductor optical amplifiers have been proposed since they possess many of the features required for the implementation of such networks. In the literature, they have been extensively studied in the context of direct detection optical communication systems. With the recent emergence of commercial coherent systems together with the advances in digital signal processing, there is an imperative need to study the performance of wavelength converters for advanced modulation formats. The objective of this thesis is to investigate the feasibility of wavelength converters based on four-wave mixing in semiconductor optical amplifiers for advanced modulation formats and subsequently propose a digital signal processing technique that aims to improve their performance. An experimental investigation of m-ary quadrature amplitude modulation (QAM) wavelength conversion is first performed. In particular, wideband wavelength conversion of 10 Gbaud 16-QAM and, for the first time, 5 Gbaud 64-QAM signals is successfully achieved over the whole C-band using a commercial semiconductor optical amplifier. The results show that the induced nonlinear distortions on the wavelength converted signal lead to a different optimal wavelength converter operating condition compared to wavelength conversion of intensity modulation formats. For wavelength conversion of advanced modulation formats, the tradeoff between the wavelength converted signal power and the nonlinearities dictates the optimal wavelength converters operating condition. The digital signal processing capabilities of coherent receivers renders possible the compensation of the signal impairments in the digital domain after detection. Making use of this, a digital post-compensation technique based on a small-signal analysis of the equations governing the gain dynamics of semiconductor optical amplifiers is developed in order to mitigate the nonlinear distortions imposed on the wavelength converted signal. The proof of concept is realized both via numerical simulations and experimental measurements of 10 Gbaud 16-QAM and 5 Gbaud 64-QAM: the post-compensation technique significantly improve the wavelength converter especially in the case of high-order advanced modulation formats such as 64-QAM. Finally, a thorough experimental investigation of the post-compensation technique performance for 5 Gbaud 64-QAM wavelength conversion is done. The results indicate that the signal quality is still improved even in the presence of a noisy signal at the wavelength converter input. Furthermore, it is shown that the optimal wavelength converter operating condition varies upon the amount of optical loss that follows. In a wavelength-routed optical network, the signal will likely pass through multiple wavelength conversion stages. The experimental investigation is extended to cascaded wavelength conversion stages and, for the first time, dual stage wavelength conversion of 5 Gbaud 64-QAM signal is performed. In this context, the proposed post-compensation technique still successfully improves the wavelength converter performance. The results of this thesis strongly suggest that wavelength converters based on four-wave mixing in semiconductor optical amplifiers, together with the use of digital signal processing techniques, is a promising candidate for advanced modulation formats wavelength conversion in future wavelength routed optical networks.
