摘要： PROBLEM TO BE SOLVED: To provide a bidirectional light emission and reception module with a low manufacturing cost.
SOLUTION: A bidirectional light emission and reception module has a light-emitting device 1 for emitting transmitting signal light, an optical fiber 8 on which the transmitting signal light is made to be incident, a light-receiving device 9 on which reception signal light emitted from the optical fiber is made to be incident, and a wavelength selection filter 4, wherein the transmitting signal light emitted from the light-emitting device is sent through the optical fiber, and the receiving signal light having a wavelength different from that of the transmitting signal light is received through the optical fiber. The bidirectional light emission and reception module has an optical device (optical isolator) constituted essentially of a reflection type polarizer 6 bonded to the end face of the optical fiber, a Faraday rotator 5 disposed integrally on the reflection type polarizer and an absorption type polarizer 3 disposed on an optical path extending between the light-emitting device and the wavelength selection filter. The reflection type polarizer has a wavelength dependency such that it functions as a polarizer for the transmitting signal light but does not function as a polarizer for the receiving signal light.
