Problems solved by technology

However, under the structure of the optical transceiver module 10, only part of the image of the light source 16 can be guided to the lens 14B through the total reflection surface TIR1, so the complete image of the light source 16 cannot be viewed from the lens 14B, thereby increasing the difficulty of assembly alignment and calibration time

Abstract

A beam-splitting integrated optical element including a shell, at least one first lens, and at least one second lens is provided. The shell includes a first lens surface, a second lens surface, at least one first reflective surface, and at least one second reflective surface. A bottom edge of each first reflective surface and a bottom edge of each second reflective surface are not connected to each other. The at least one first lens is disposed on the first lens surface. The at least one second lens is disposed on the second lens surface, and each second lens has a second optical axis. Each second reflective surface is located at at least one side of the corresponding second optical axis and located on a transmission path of only a portion of a first beam. The invention is further directed to an optical transmitter module having a beam-splitting integrated optical element which can provide a preferable yield rate, low alignment difficulty and short alignment time.

Description

technical field [0001] The invention relates to an integrated optical component with light splitting function and an optical transceiver module. Background technique [0002] With the advancement of communication technology, communication methods are no longer limited to using electrical signals. Recently, an optical communication technology that realizes signal transmission with optical signals has been developed. Since the transmission rate and distance of light are much higher than that of electrons, optical communication has gradually become the mainstream of the market. Based on high bandwidth requirements, the demand for optical transceiver modules that can transmit a large number of optical signals is increasing day by day. In order to ensure the stability of signal transmission, the optical transceiver module often needs to monitor the optical power synchronously. The optical transceiver module using the edge-emitting laser can use the back-emitting light of the e...
