Abstract
In assembly of a number of optical devices (optical waveguide devices) to fabricate an optical module, the fabrication method of the optical module comprising: filling a plurality of openings for device mounting, the openings being formed on a platform, with a transparent liquid material; putting an optical waveguide device into at least one of the plurality of openings; and carrying out an active alignment process with the intention that a fine adjustment (waveguide alignment) of the position of each optical device can be realized with ease.
Claims15
A method for fabricating an optical module comprising:
- filling a plurality of openings for device mounting, the openings being formed on a platform, with a transparent liquid material;
- placing an optical waveguide device into one of the plurality of openings;
- and
- carrying out an active alignment process for the optical waveguide device by using light passing through the optical waveguide device and one or more of the transparent-liquid-material-filled openings.
An optical module comprising:
- a platform including an optical waveguide having a plurality of openings for device mounting, the openings being formed at predetermined distances and capable of being filled with a liquid material;
- and
- an optical waveguide device mounted in at least one of the plurality of openings,
- wherein a space between the optical waveguide device and the at least one opening is filled at least in part with a transparent material.
An optical module comprising;
- a platform having a plurality of openings for device mounting, the platform including a substrate, at least three optical waveguides formed in series on the substrate, and sidewall sections formed on said substrate such that the plurality of openings are formed between said optical waveguides, the openings being formed at predetermined distances and capable of being filled with a liquid material;
- and
- an optical waveguide device mounted in at least one of the plurality of openings,
- wherein a space formed between the optical waveguide device and the at least one opening is filled with a transparent material.
A platform for an optical module comprising:
- a plurality of openings for device mounting, the openings being formed at predetermined distances and capable of being filled with a liquid material;
- a substrate;
- and a waveguide formed on the substrate, the waveguide having the plurality of openings for device mounting arranged such that a light path includes at least a portion of the waveguide and the plurality of openings.
A platform for an optical module comprising:
- a plurality of openings for device mounting, the openings being formed at predetermined distances and capable of being filled with a liquid material;
- a substrate;
- at least three optical waveguides formed in series at predetermined distances on said substrate;
- and
- sidewall sections formed on said substrate such that said plurality of openings are formed between the optical waveguides.
