Abstract
An optical structure for the bidirectional coupling of light between each of a multiplicity of optical fibers and corresponding individual thin-film waveguides to achieve a leaky wave coupling from one guided mode structure to a second guided mode structure. The structure is particularly suited for fabrication by planar deposition and etching techniques and features the precise axial alignment of the optical elements by inserting the fibers in etched V-grooves in the substrate upon which are deposited the waveguides.
