摘要 | The polarization control of vertical-cavity surface-emitting lasers with high power emission has been demonstrated by using metal grating to import non-isotropic gain. The grating with a period of 186 nm and a duty ratio of 0.5 was fabricated on the GaAs-cap layer to provide additional reflectance for H-polarization. The pairs of P-distributed Bragg reflectors were reduced to realize the maximum difference threshold gain of two orthogonal polarizations. A polarization ratio of 3 with an output power of 860 mW at continuous-wave operation was demonstrated at room temperature, and the high-order modes were suppressed. As a result, the far-field beam divergence was suppressed to 12 degrees. |
