Experimental investigation of stability properties for a semiconductor laser with optical feedback

Abstract

The stability limits for a semiconductor laser exposed to optical feedback have been measured as a function of the feedback level and the phase of the reflected field. The experimental results are in good agreement with a detailed theoretical analysis. They include a determination of the absolute feedback level in a practical set-up and of the R-parameter, which for the actual laser is found to be −3.0 ± 0.3.
