Paper Abstract

In this paper, for the first time, we present a theoretical investigation of optimization and stabilization of wavelength conversion bandwidth based on a counter-propagating configuration, which correspond to second-order wavelength conversion architectures with propagation directions of signal and idler beams being opposite. Optimized example for two-, four-, six- and ten-segment chirp gratings are given, respectively. The stabilization of signal bandwidth can be realized by adjusting the pump wavelength. The numerical results show that the counter-propagating difference frequency generation (CDFG)-based wavelength converter with chirped modulation is an excellent candidate for wavelength division multiplexed (WDM) application.
