Abstract:
A method for producing an optical device comprising:lithographically forming a multiplicity of waveguides onto an gallium arsenide substrate; mounting said gallium arsonide 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 base 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.
