| 英文摘要 | An optoelectronic device includes a planar active element, a vertical waveguide surrounding the active element in the vertical direction, and a lateral waveguide comprising at least one active section and at least one filter section following each other in the longitudinal direction. At least part of the active element within the active section generates optical gain in response to above-threshold pumping. The broad lateral waveguide in the active section can localize multiple lateral optical modes. In the filter section, no lateral confinement is provided for the lateral optical modes. The device further comprises means to ensure low absorption loss in the filter section and, therefore, ensure high efficiency. In one embodiment low absorption loss is achieved by pumping of at least part of the active element within the filter section. In another embodiment, the active element has small overlap with the vertical optical modes. |
