Experimental evaluation of all-optical asynchronous and synchronous memories

Abstract

We experimentally demonstrate the accuracy of an all-optical S-R latch and an optical S-R flip-flop based on hybrid integrated Mach-Zehnder Interferometers, with Semiconductor Optical Amplifier in each arm (MZI-SOA). The performance of both bistable devices will be studied and compared in terms of extinction ratio and switching times.

Advanced optical modulation and format conversion

“…Exploiting non-linear effects in SOAs and MZI-SOAs has enabled the demonstration of integrated optical buffers, making GHz flip-flop operation possible [101]. The MZI-SOA has become an important element to performs a variety of optical logic functions and provides high Extinction Ratio (ER), requires low switching energies to operate and have regenerative capability and compactness [8,[102][103][104]. An optical logic Exclusive OR (XOR) gate, based on a hybrid integrated MZI-SOA, served has the starting point for the modulation format conversion scheme proposed in Chapter 5.…”
