Polarization-Independent Wavelength-Tunable Vertical Cavity Surface Emitting Laser Based on Two-Dimensional Grating
To realize a polarization-independent vertical cavity surface emitting laser (VCSEL), the polarization-independent grating and the half-VCSEL are integrated. Based on the rigorous coupled wave analysis, the effects of grating parameters on the reflection characteristics of a polarization-independent two-dimensional grating are analyzed. The 210 nm high-reflection bands of the polarization-independent two-dimensional grating for a grating period of 691-719 nm and a grating width of 408.73-467.60 nm are obtained via analog computation. Then, the polarization-independent two-dimensional grating and the half-VCSEL with a 1.55-μm central wavelength are integrated to develop a polarization-independent wavelength-tunable VCSEL with the 1.55-μm central wavelength. The calculation based on an optical transmission matrix indicates that the wavelength-tuning range of 93 nm can be realized for the polarization-independent wavelength-tunable VCSEL.
