VERTICAL CAVITY SURFACE EMITTING LASER SEMICONDUCTOR DEVICE, LIGHT TRANSMITTING MODULE AND LIGHT TRANSMITTING APPARATUS

摘要

An embodiment of the present invention relates to a vertical cavity surface emitting laser (VCSEL) semiconductor device, a light transmitting module, and a light transmitting apparatus. The VCSEL semiconductor device according to an embodiment of the present invention includes a light emitting structure and a guide part. The light emitting structure according to an embodiment of the present invention includes a first conductive DBR layer, a second conductive DBR layer, and an active layer disposed between the first conductive DBR layer and the second conductive DBR layer. The guide part according to an embodiment of the present invention is disposed on the upper surface of the light emitting structure. The light emitting structure according to an embodiment of the present invention includes a light emitting aperture which emits light in a direction perpendicular to the upper surface of the light emitting structure, and the guide part provides a through hole with a larger diameter than the diameter of the light emitting aperture. The through hole is provided on the light emitting aperture. Accordingly, the present invention can easily perform optical alignment.;COPYRIGHT KIPO 2018
