OPTICAL TRANSMISSION MODULE
Document Type and Number:
WIPO Patent Application WO/2024/053467
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide an optical transmission module which is small-sized and highly integrated and which can perform demultiplexing and multiplexing across multiple wavelengths. An optical transmission module (100) according to the present disclosure has: a first lens part (30) which refracts and focuses transmitted light between an optical fiber (90) and the first lens part; a second lens part (60) disposed on the optical axis of the first lens part (30) so as to face the first lens part; a receptacle substrate (51) having a contact plug (52) which positions an end surface of the optical fiber at the focal point of the second lens part (60) and which connects the optical fiber; a first light guide body (11) disposed on a surface, of the first lens part (30), not facing the second lens part; a demultiplexing/multiplexing part (20) which is disposed on a surface, of the first light guide body (11), not having the first lens part disposed therein and which demultiplexes or multiplexes the transmitted light of the first lens part; and a plurality of photoelectric elements (21a, 21b) which are disposed in the demultiplexing/multiplexing part (20) and which performs at least one of light emission to the first lens part and light reception from the first lens part, via the demultiplexing/multiplexing part and the first light guide body.
