摘要：
A novel class of semiconductor light-emitting devices, or "tilted cavity light- emitting devices" is disclosed. The device includes at least one active element, generally placed, within a cavity, with an active region (505) generating an optical gain by injection of a current (513) and two mirrors (502, 506). The device generates optical modes (520) that propagate in directions, which are tilted with respect to both the p-n junction plane and the direction normal to this plane. A light-emitting diode is also disclosed, where the cavity and the mirrors are designed such that transmission of generated optical power within a certain spectral range and within a certain interval of angles to the substrate is minimized. Transmission of optical power within a certain spectral range, which corresponds to the emission range of the light-emitting active medium and within a certain interval of angles out of the device, is optimized to achieve a required output power level (523).

公开了一类新颖的半导体发光器件或“倾斜腔发光器件”。 该装置包括通常放置在空腔内的至少一个有源元件，有源区域（505）通过注入电流（513）和两个反射镜（502,506）产生光学增益。 该装置产生在相对于p-n结平面和垂直于该平面的方向倾斜的方向上传播的光学模式（520）。 还公开了一种发光二极管，其中空腔和反射镜被设计成使得在特定光谱范围内并且在与衬底的一定角度范围内的所产生的光功率的传输最小化。 对与发光有源介质的发射范围相对应的特定光谱范围内的光功率的传输在设备外的一定角度范围内被优化以实现所需的输出功率电平（523）。
