“…All-optical Boolean XOR gate is the core logic unit to implement various alloptical systems such as binary adders, binary counters and decision circuits, as well as encoders and bit-pattern recognition circuits. A revolution has been brought about in all-optical information processing systems with the help of the discovery of ultra high speed all-optical switches based on cross phase modulation (XPM) [1][2][3][4][5]. Various schemes of all-optical XOR operation have been reported using semiconductor optical amplifier-Mach-Zehnder interferometer (SOA-MZI) [6][7][8][9][10][11][12][13], Terahertz Optical Asymmetric Demultiplexer (TOAD) based interferometric switch [14,15], four wave mixing (FWM) in a SOA [16], ultrafast nonlinear interferometer (UNI) [17][18][19] and bismuth oxide based nonlinear fiber (Bi-NLF) [20].…”

“…The Mach-Zehnder interferometer has two spatially separated optical arms. Stable operation is possible with this switching device only in a monolithic or hybrid integration of the interferometric configuration [41,42]. However, with use of an additional active phase stabilization, a hybrid fiber-chip Mach-Zehnder interferometer switch was also operated as demultiplexer in a 160 Gbit/s, 160 km fiber transmission experiment [43].…”

“…9) is one of the most promising candidates. It enables to realize a compact and potentially low cost DEMUX by monolithic integration of the SOAs and the interferometer structure [41,[61][62][63][64][65]. Also a hybrid-integrated SOA-MZI, called hybrid integrated symmetric Mach-Zehnder (HI-SMZ) has been realized and demultiplexing of data signals up to 336 Gbit/s was demonstrated [66][67][68].…”

The authors report on all-optical switching devices based on semiconductor optical amplifiers (SOA) in applications for optical time division multiplexing (OTDM) transmission technology. The report includes a discussion on the basic properties of an SOA on the nonlinear processes of cross-phase modulation and four-wave mixing in the SOA used for all-optical switching and on the application of the SOA as demultiplexer add-drop multiplexer clock recovery and wavelength converter. The devices considered here operate at data rates in excess of \Gb80 where electrical signal processing is not available today

“…[34] The input signal can be fully utilized without any wasted power if both the output signals have high enough signal quality for further processing. Since the UNI has an assured balance in phase-shift because it consists of only one SOA, it can provide two output signals having equal signal quality with much less difficulty.…”

Semiconductors have large optical nonlinearity with response speed in the several tens of picosecond range, making them ideal use as all-optical regenerators and wavelength converters. We theoretically and experimentally investigated optical nonlinearities induced by carrier dynamics both in forward biased semiconductor waveguide (SOA) and in reverse biased semiconductor waveguide (EAM). We made a detailed theoretical study of carrier dynamics in semiconductor waveguides by using the newly developed time-dependent transfer matrix method. To confirm the simulation results, we propose utilizing a polarization discriminating delayed interferometer (PD-DI) configuration as a simple technique for measuring optical nonlinearities such as cross gain modulation (XGM), cross absorption modulation (XAM), and cross phase modulation (XPM). In the first part of the paper, we reviewed SOA-based regenerators. As expected from the simulation results, we confirmed that injection of the transparent assist light was very effective in reducing of the SOA gain recovery time of down to a few tens of picoseconds. We further demonstrated 40 Gbit/s regeneration using an SOA-one-arm MZI (so-called UNI) configuration. The superior regeneration capability of two-stage UNI was successfully confirmed by a recirculating loop experiment up to 30,000 km with 150 regenerations. In the latter part of the paper, we reviewed all-optical regenerators using EAM. A bit-synchronized rf-driven XAM 3R regenerator consisting of only one EAM for both gating and timing correction was demonstrated at 20 Gbit/s. An EAM in conjunction with delayed interferometer configuration, which utilizes XPM as well as XAM in the EAM, has structurral simplicity and fast regeneration operability up to 100 Gbit/s. The fast response of EAM allows the optical regeneration with a small pattern word effect. 498Masashi Usami and Kohsuke Nishimura
