Abstract

An optical device having a multiplicity of optical fibers fixed in respective grooves in a first substrate in a predetermined arrangement in an optical fiber plane. A second substrate is fixed onto the first substrate such that an edge of the second substrate extends beyond the ends of the optical fibers. A lens assembly including a third substrate, and a lens fixed on the third substrate is mounted on the second substrate such that the lens lies in a second predetermined arrangement with respect to the ends of the optical fibers and is spaced from them in a plane perpendicular to the optical fiber plane with a first degree of accuracy and in the optical fiber plane with a lesser second degree of accuracy.

Dependent claims

A method for producing an optical switch comprising:

lithographically forming a multiplicity of waveguides onto an gallium arsenide substrate;
mounting said gallium arsenide substrate onto a base substrate;
and
precisely positioning a fiber optic module, having a multiplicity of optical fiber ends and an optical mode modifying lens, onto said base substrate, including:
using at least one external positioner, manipulating at least one of said fiber optic module and said base substrate relative to the other such that the mode of each optical fiber matches the mode of at least one corresponding waveguide with relatively low light loss;
and
fixing said fiber optic module in a desired relative position on said bas substrate independently of said external positioner;
and
disengaging said at least one external positioner from said at least one of said fiber optic module and said base substrate.
