Title:
OPTICAL BRANCHING/COUPLING INSTRUMENT AND OPTICAL TRANSMISSION/RECEPTION MODULE
Document Type and Number:
WIPO Patent Application WO/2017/155007
Kind Code:
A1
Abstract:
Provided is an optical branching/coupling instrument in which optical transmission quality is improved by preventing a reduction in optical transmission quality, said reduction being due, for example, to an optical waveguide core affecting a light of another optical waveguide core in the vicinity of a joining section of the two optical waveguide cores. This optical branching/coupling instrument comprises: a first optical waveguide 1 that is provided extending from one end side to another end side; a second optical waveguide 2 that is provided extending on a separate route from the same one end side to the other end side, the other end side of said second optical waveguide 2 being joined to the other end side of the first optical waveguide 1; and a cladding layer 3 that covers the periphery of the first optical waveguide 1 and the second optical waveguide 2, wherein the first and second optical waveguides comprise a cured product of a photocuring resin.
