“…Electrical filter-based devices are now under deep study and are expected to have a significant impact at the high bit rate optical link receiving edge. These devices are in general based on analog domain transversal filters that are able to operate at higher bit rate signals (10 Gbit/s, 40 Gbit/s and potentially above) [36,37]. A major advantage of EDC is the possibility of electronic adjustment, making it in principle possible to compensate for changes in receiver response or other distortions due to ageing and/or temperature variations.…”

We review the research progress concerning some fundamental issues related to polarization-mode dispersion (PMD) in high-speed fiber-optic transmission systems. We pay particular attention to issues such as the PMD-induced pulse broadening, PMD measurement and emulation, as well as PMD compensation. An electrical equalization technique based on a transversal filter and an optical technique based on a nonlinear chirped fiber Bragg gratings for PMD compensation will be discussed.

“…In the most commonly used scenarios, where the multistage amplifier is constructed from transistors of equal gains and the phase velocities of both lines are equal, the amplified signal from each of the transistors are all in phase and they add in the forward direction towards the output [6], [7], [10], [11]. It has also been shown that the input and output ATLs may also be purposively kept unequal, to provide specific gain [12] and filtering advantages [13], [14], with application in specialist communication systems.…”

This paper highlights the gain-bandwidth merit of the single stage distributed amplifier (SSDA) and its derivative multiplicative amplifier topologies (i.e. the cascaded SSDA (C-SSDA) and the matrix SSDA (M-SSDA)), for ultra-wideband amplification. Two new monolithic microwave integrated circuit (MMIC) amplifiers are presented: an SSDA MMIC with 7.1 dB average gain and 200 GHz bandwidth; and the world's first M-SSDA, which has a 12 dB average gain and 170 GHz bandwidth. Both amplifiers are based on an Indium Phosphide DHBT process with 250 nm emitter width. To the authors best knowledge, the SSDA has the widest bandwidth for any single stage amplifier reported to date. Furthermore, the three tier M-SSDA has the highest bandwidth and gain-bandwidth product for any matrix amplifier reported to date.

“…In 1997, Jamani et al [31] and Borjak et al [30] reported the first implementations using reverse-gain mode and forward-gain mode (in traveling-wave amplifier terminology), respectively. The latter group later switched to the reverse-gain mode architecture [32]. In 2000, Lee and Freundorfer introduced the Gilbert cell to generate both positive and negative weights [33].…”

Abstract-Intersymbol interference (ISI) caused by intermodal dispersion in multimode fibers is the major limiting factor in the achievable data rate or transmission distance in high-speed multimode fiber-optic links for local area networks applications. Compared with optical-domain and other electrical-domain dispersion compensation methods, equalization with transversal filters based on distributed circuit techniques presents a cost-effective and lowpower solution. The design of integrated distributed transversal equalizers is described in detail with focus on delay lines and gain stages. This seven-tap distributed transversal equalizer prototype has been implemented in a commercial 0.18-m SiGe BiCMOS process for 10-Gb/s multimode fiber-optic links. A seven-tap distributed transversal equalizer reduces the ISI of a 10-Gb/s signal after 800 m of 50-m multimode fiber from 5 to 1.38 dB, and improves the bit-error rate from about 10 5 to less than 10 12 .
