英文摘要：

We demonstrate a novel oxide confined GaAs-based photonic crystal vertical cavity surface emitting laser （PC-VCSEL） operating at a wavelength of 850 nm based on coherent coupling. A ring-shaped light-emitting aperture is added to the conventional PC-VCSEL, and coherent coupling is achieved between the central defect aperture and the ring-shaped light-emitting aperture. Measurements show that under the continuous-wave （CW） injected current of 20 mA, a high power of 2 mW is obtained, and the side mode suppression ratio （SMSR） is larger than 20 riB. The average divergence angle is 4.2° at the current level of 20 mA. Compared with the results ever reported, the divergence angle is reduced.
