Research on polarization control of tunable VCSEL with a top wave-like mirror structure

In this paper, we designed a novel tunable VCSEL structure with a top wave-like mirror for polarization control. Based on rigorous coupled-wave theory, the reflection characteristics of the top wave-like mirror structure for different polarization modes was analyzed. The wave-like structure was designed and optimized to control the output polarization mode of tunable VCSEL. The results show the threshold gain of TM mode is always greater than the TE mode during 84.5nm wavelength tuning range, the maximum increase is more than 10 times. It is indicated that the designed structure of tunable VCSEL can effectively realize stable polarization mode.
