Detuned Grating Single-Mode Laser With High Immunity to External Optical Feedback
Abstract
In this paper, we report a novel single-mode laser with high immunity to external optical feedback following the principle of active-filter-tuned oscillator. Within the conventional Fabry-Pérot (FP) cavity, a high-Q bandpass filter formed by two tilted gratings with detuned Bragg wavelengths is embedded, and the resultant mode selection mechanism can purify the lasing spectrum by eliminating all but one of the FP cavity modes near the peak …
