Optical device having mesas |
摘要 |
An optical device and method for fabricating an optical device. The optical device comprising: a semiconductor material comprising an active layer configured to emit light when an electrical current is applied to the device and/or to generate an electrical current when light is incident on the active layer, wherein the semiconductor material comprises a first surface and an opposed second surface, from which light is emitted from and/or received by the device, and wherein the first surface defines a first structure comprising the active layer and configured to reflect light emitted from the active layer toward the second surface and/or to reflect light received by the device toward the active layer, and the second surface defines a second structure configured to permit light incident on the second surface at an angle outside a critical angle range to the planar normal to pass therethrough. |

1. An optical device comprising:
a semiconductor material comprising an active layer configured to emit light when an electrical current is applied to the device and/or to generate an electrical current when light is incident on the active layer, wherein the semiconductor material comprises a first surface and an opposed second surface, at which light is emitted from and/or received by the device, wherein the first surface defines a first structure comprising the active layer and configured to reflect light emitted from the active layer toward the second surface and/or to reflect light received by the device toward the active layer, and the second surface defines a second structure configured to permit light incident on the second surface at an angle outside a critical angle range to the planar normal to pass therethrough, the first and second structures comprising mesas with truncated tops, and wherein the mesas have a circular footprint and the footprint of the mesa of the second structure has a larger diameter than the footprint of the mesa of the first structure. |
