Paper Abstract

We investigate nondegenerate four-wave mixing and the resulting high efficiency of wavelength conversion in a semiconductor-optical-amplifier integrated distributed feedback laser, which is one of the latest achievements of photonics technology. For analyzing the amplifier we use a finite-difference beam propagation method based on solution of a modified nonlinear Schrödinger equation, and for the laser we use a coupled-wave approach. We investigated wavelength conversion up to 4-THz pump-probe detuning with lossless conversion up to 400-GHz detuning and a conversion efficiency of -4.8 dB at 1-THz pump-probe detuning. For calibration and verification of the software developed in this study, we have used experimental measurements reported from MIT electronics and Fujitsu research laboratories on a similar device. We have successfully estimated the conversion efficiency of the tested device.
