Abstract:
A package structure of a hybrid device in a optical signal transmitter, comprising:a metal header, wherein the metal header has a first metal rod, a second metal rod, and a third metal rod, and the metal rods are insulated with the metal header by an insulator; a submount insulator disposed on the metal header, wherein an electric connect region is formed on the submount insulator; a surface emitting laser disposed on the submount insulator and coupled to the metal rods; a pair of photodiodes disposed on the submount insulator and coupled to the metal rods, wherein the pair of photodiodes are on both sides of the surface emitting laser, and the photodiodes and the surface emitting laser have the same electric connect region; and a package assembly disposed on the metal header, and packaging the surface emitting laser and the photodiodes, wherein portion of laser light from the surface emitting laser is reflected to the photodiodes, wherein the first metal rod is connected to the surface emitting laser through a first wire, the second metal rod is connected to the submount insulator through a second wire, and the third metal rod is connected to the pair of photodiodes through a third wire and a forth wire, so that the first metal rod, the SEL, the submount insulator and the second metal rod are formed an electric channel with an external circuit, and the second metal rod, the submount insulator, the photodiodes and the third metal rod are formed another electric channel with the external circuit.
