摘要
In this paper, the thermal analysis of metal-grating stable-polarization vertical cavity surface emitting laser is theoretically and experimentally performed. The pairs of P-DBRs are reduced to achieve the maximum difference threshold gain of two orthogonal polarizations. As a result, more excellent temperature characteristics have been obtained, to be specific, the temperature of active region with the aperture of 150um is reduced from 357 K of normal device to 343 K at the current of 4A. The wavelength/current is 0.57 nm/A of grating device which is smaller than that of 0.71 nm/A of normal device. Better near field distribution of grating devices has been displayed owing to the better temperature characteristic.
