Semiconductor light receiving device, optical receiver module and manufacturing method thereof
Abstract:
Provided are a semiconductor light receiving device, an optical receiver module, and a manufacturing method thereof in which characteristics of the device are improved when the device has a structure in which a mesa structure including layers formed of a common material is buried by a buried layer. The semiconductor light receiving device includes the mesa structure including the layers formed of a commonmaterial, the layers including an absorbing layer, the mesa structure being buried by the buried layer formed so as to surround side surfaces of the mesa structure. The mesa structure has a cross section having a forwardly tapered portion and a reversely tapered portion.
