| 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 db. the average divergence angle is 4.2 degrees at the current level of 20 ma. compared with the results ever reported, the divergence angle is reduced. |
