Abstract
An optical waveguide module in which transmitted signal light emitted from a laser light-emitting element 4 passes through a first optical waveguide 3a and a second optical waveguide 3b to strike a transmitting/receiving medium 5 such as an optical fiber, and a signal light from the transmitting/receiving medium 5 passes through the second optical waveguide 3b and is received by a light-receiving element 7, the optical waveguide module comprising, a first light-blocking resin covering part 12, which covers a light-emitting coupling part 11a coupling the laser light-emitting element 4 and the first optical waveguide 3a, and a second light-block resin covering part 14, which covers a light-receiving coupling part 13a coupling the light-receiving element 7 and the second optical waveguide 3b.
Claims6
An optical waveguide module in which transmitted signal light emitted from a laser light-emitting element passes through a first optical waveguide and a second optical waveguide to strike a transmitting/receiving medium such as an optical fiber, and a signal light from said transmitting/receiving medium passes through said second optical waveguide and is received by a light-receiving element, said optical waveguide module comprising:
- a first light-blocking resin covering part, which covers a light-emitting coupling part coupling said laser light-emitting element and said first optical waveguide, and
- a second light-block resin covering part, which covers a light-receiving coupling part coupling said light-receiving element and said second optical waveguide.
An optical waveguide module in which transmitted signal light emitted from a laser light-emitting element passes through a first optical waveguide and a second optical waveguide to strike a transmitting/receiving medium such as an optical fiber, and a signal light from said transmitting/receiving medium passes through said second optical waveguide and is received by a light-receiving element, said optical waveguide module comprising:
- a light-blocking plate, disposed above said first optical waveguide, which blocks transmitted signal light missing said light-emitting coupling part coupling said laser light-emitting element and said first optical waveguide.
