Characters of the semiconductor laser with strong feedback
Abstract:This paper investigates the dynamical behaviors of a laser diode (LD) with strong feedback. The spectra, coherence length, and dynamical output power of a LD with different feedback are measured experimentally. It is found that the LD will return back to stable single mode when feedback is strong enough. The Lang-Kobayashi equations are modified to analyze the output of the LD with strong feedback. The good coincidences between the experiment results and the theoretical expectations are found. The results obtained here will give useful information for using the LD as both light source and detector.
