“…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].…”

“…[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.…”
