Abstract

Semiconductor optical amplifiers are important for wide range of applications including optical networks, optical tomography and optical logic systems. For many of these applications particularly for optical networks and optical logic high speed performance of the SOA is important. The speed of operation of SOA is limited by the gain and phase recovery times in the SOA. We have demonstrated higher speed operation (i) for SOAs with a carrier reservoir layer, (ii) for SOAs with a multi-quantum well modulation doped active region, and, (iii) for SOAs with a quantum dot (QD) active region. The multi-quantum well SOA has been integrated with InGaAsP/InP based waveguides to build Mach- Zehnder interferometers (MZI). XOR optical logic has been demonstrated at 80 Gb/s using these SOA-MZI structures. XOR operation has been analyzed by solving the rate equation of the SOA, for SOAs with both regular and QD active region. Mach-Zehnder interferometers fabricated using SOA with quantum dot active region (QD-SOA) can be used for XOR operation at 250 Gb/s. Pseudo random bit stream (PRBS) generation using both regular and QD-SOA have been studied and their performance modeled. The model shows QD-SOA based devices can be used to produce PRBS generators that operate near 250 Gb/s.
