Title: Optical coupler module
Inventor: ISHII TOKUO
IPC: G02B6/28
Filed: 1988-03-07
Abstract: PURPOSE:To reduce the decline of the optical coupling quantity by making the central part of light reflecting element light transmissivity and making the periphery of the control part a reflecting section. CONSTITUTION:A light transmissivity property is given to the circular or elliptic central part of a light reflecting element 27 and a reflecting section is formed at the periphery of the central part. Since this optical coupler module is constituted in such a way, the reflecting section of the element 27 mainly reflects the high-order mode of the parallel rays of light emitted from a light emitting element 23 and converted by a 3rd lens 26 and couples the rays of light to an optical fiber through a 1st lens 24. At the same time, the reflecting section works so as to intercept the reflecting rays of light toward a light receiving section from the optical fiber side. Moreover, the central part of the element 27 mainly passes the low-order mode of the parallel rays of light emitted from the optical fiber 21 and converted by the 1st lens 24 and couples the rays of light to the light receiving section 22 through a 2nd lens 25. Therefore, the crosstalk from the light emitting element 23 to the light receiving section and the loss in the light coupling quantity from the optical fiber to the light receiving section can be reduced.
