Abstract:
1. A method of producing a light source comprising: providing a first waveguide device, implemented in gallium arsenide; fiberlessly coupling light from a second waveguide device to said first waveguide device, said second waveguide device being a discrete element which is mechanically mounted in a desired position with respect to said first waveguide device; enclosing said first waveguide device and said second waveguide device within a housing together with output optics operative to direct light from said first waveguide device into an optical fiber extending outwardly from said housing; and mounting said second waveguide device and said first waveguide device on parallel surface mountings, said parallel surface mountings including mutually facing surfaces which lie in parallel planes which are perpendicular to an optical axis of a light beam propagating from said second waveguide device towards said first waveguide device, said fiberlessly coupling comprising: using at least one external manipulator, manipulating at least one of said first waveguide device and said second waveguide device relative to the other such that the output light beam of said second waveguide device enters said first waveguide device with relatively low light loss; fixing said first waveguide device and said second waveguide device in desired relative positions independently of the external manipulator; and disengaging said at least one external manipulator from said light source.
