Abstract: Micromachined depressions are created at a surface of lithium crystal/wavide composite and suitable optical components are inserted into these depressions and precisely aligned with waveguides so that light can be coupled into and out of the waveguides without fiber pigtails. The optical components can be independent or be a part of a mating unit which may incorporate appropriate electronics to support the optical components. Instant invention produces an application-ready integrated optics chip without the necessity for labor-intensive pigtailing or for separate provision of supporting electronics after the user acquires commercially available lithium crystal/waveguide composite.
