BMDO Modeling and Simulation of Multiwavelength Conversion in Semiconductor Laser Optical Amplifiers for Logic, Switching, Communication.

摘要

This grant was an AASERT funded project that supported one graduate student in association with parent grant F49620-96-1-0168. The program achieved several wavelength conversion demonstrations via four-wave mixing in semiconductor optical amplifiers (SOAs) and computer simulation to describe multiwavelength propagation in SOAs with wavelength dependent gain and gain saturation. They studied the effect of generation of composite dynamic gratings on the FWM wavelength conversion process and demonstrated the following FWM milestones: single channel conversion of 12, Gbps pseudo-random bit sequence (PRBS) data, single pump/multichannel probe conversion of four 2.5 Gbps channels a simultaneous conversion of two 2.5 Gbps data channels using two spectrally segmented FWM process within a single amplifier. The later demonstration represents a significant milestone in the direction of our program objectives. The team also implemented several models for multiwave propagation in SOAs that account for wavelength dependent gain asymmetry, saturation power, small signal modulation, and pulse propagation.
