Optical transmit/receive module and method of fabricating the same

Abstract

An optical module receives light traveling through an optical fiber in two ways. A coupler is provided in a case member and is attached to an end surface of a ferule having the optical fiber. The coupler allows light of a first wavelength to pass therethrough along a first optical axis of the optical fiber and reflects light of a second wavelength so that reflected light travels along a second optical axis perpendicular to the first optical axis. A light emitting element is provided so as to be located on one of the first and second optical axes. A light receiving element is provided so as to be located on the other one of the first and second optical axes.
