Abstract
Disclosed is an optical module comprising, an optical waveguide on the upper side of a substrate; a cutout with at least two slant surfaces, passing at least the core of the optical waveguide; and a film-filter above the cutout. Constructions of bi-directional multi-wavelength optical transmitter-receiver assembly using the optical module as a unit element are also provided in variety on a planar substrate. According to this invention, a bi-directional multi-wavelength transmitter-receiver, which is compact, reliable, excellent in the optical performance and simple in the alignments between the composing elements, can be produced.
Claims8
An optical module, comprising:
- a first and a second optical waveguide approaching each other on the upper side of a substrate;
- a third and a fourth optical waveguide approaching each other, having the approaching area which is connected to the first and the second optical waveguide in extension;
- a cutout at the approaching area, comprising a first slant for cutting the first and second optical waveguide with a first cutting angle, and a second slant for cutting the third and fourth optical waveguide with a second cutting angle;
- a film-filter formed on the approaching area;
- and
- an optical device on or under the approaching area.
