Paper Abstract

Wide bandwidth and high-resolution analog to digital converters (ADCs) are required for the next generation of sensor systems. Progress at advancing the electronic ADC modules has been very slow due in large part to the difficulties in fabricating the electronic circuitry required for very high resolution and high sampling rate converters. It is anticipated that the use of photonic ADCs will far surpass the performance of electronic ADCs in terms of both sampling speed and resolution. We have recently designed a novel photonic ADC module that incorporates the use of semiconductor saturable absorbers to perform the data quantization at speeds in the tens of GHz regime. Experimental material characterization results including the nonlinear transmission and the recovery time of the semiconductor saturable absorbers use din the data conversion process will be presented. Different material parameters will also be analyzed including the effects of low temperature growth, band-edge position, and strain on these material properties.
