Title:
OPTICAL TRANSMISSION MODULE
Document Type and Number:
Japanese Patent JP2016178218
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical transmission module that controls plural light emission elements so that the intensity of light emitted from each of the plural light emission elements are more constant.SOLUTION: An optical transmission module for converting an electrical signal into an optical signal and outputting the optical signal includes: a package 101; a plurality of light emitting elements 200 for emitting light in the package 101; a plurality of light receiving elements 300 each having a light receiving surface 301 to which a part of the light is incident in the package 101 in order to monitor the optical output of each of the plurality of light emitting elements 200; and light-shielding members 400 which are respectively provided to the plural light receiving elements 300 so as to avoid the light receiving surfaces 301.SELECTED DRAWING: Figure 2
