Effects of the residual Fabry-Perot cavity modes on the non-degenerated four-wave mixing in DFB semiconductor lasers

摘要

In this paper, the influence of the residual Fabry-Pdrot (F-P) cavity mode on the non-degenerated four-wave mixing (FWM) in DFB semiconductor lasers (DFB-SLs) has been investigated experimentally. The results show that the FWM can be enhanced obviously when the probe wavelength matches one of the F-P cavity modes, and the high conversion efficiency can be achieved even if the frequency detuning between the injection probe frequency and free-running frequency of the DFB-SL is up to THz.
