Abstract:
In optoelectronics, a method of fabricating an electrooptically active glass fiber segment comprising the steps, in any order of:inducing a second-order nonlinearity in said glass fiber segment; andplacing a portion of said glass fiber segment between two electrodes, wherein said placing step includes the steps of:a) etching a ""D"" fiber such that the surface of the flat side is close to the core;b) gluing said polished ""D"" fiber to a flat substrate with a conductive surface with the ends of said fiber extending beyond the substrate;c) depositing a layer of dielectric material on said substrate containing said polished ""D"" fiber, such that the ""D"" fiber is substantially covered by said dielectric;d) polishing the fiber/dielectric structure of step c) to provide a planar surface and close access to the fiber core on the side opposite said substrate;e) depositing a second metal layer on said planar surface over said fiber, thereby forming an electrode.
