PROCESS TO ASSEMBLE OPTICAL RECEIVER MODULE

摘要

An optical receiver module that receives wavelength multiplexed light and a process to assemble the optical receiver module are disclosed. The optical receiver module provides a coupling unit to collimate the wavelength multiplexed light and a device unit that installs an optical de-multiplexer and photodiode elements within housing. The front wall of the housing through which the wavelength multiplexed light passes is polished in a right angle with respect to the bottom of the housing.

1. A process to assemble an optical receiver module that provides a coupling unit to collimate a received wavelength multiplexed signal, and a device unit including an optical de-multiplexer, a mirror, a photodiode (PD) array, and a housing, the optical de-multiplexer generating a plurality of optical signals each having a specific wavelength different from others by de-multiplexing the wavelength multiplexed signal provided from the coupling unit, the mirror reflecting the optical signals toward the PD array, the PD array integrating a plurality of PD elements for detecting respective optical signals provided from the mirror, the housing enclosing the optical de-multiplexer, the mirror, and the PD elements therein, the housing having a side wall and a bottom, the side wall fixing the coupling unit thereto, the process comprising steps of:
aligning the optical de-multiplexer on a carrier that mounts the mirror in an edge thereof such that an optical input port at which the collimated wavelength multiplexed signal enters makes a preset angle with respect to the edge of the carrier; aligning the edge of the carrier with the side wall of the housing; and setting the carrier in the housing.
