ORGANIC CRYSTAL COMPOUND OPTICAL WAVEGUIDE AND METHODS FOR ITS FABRICATION

摘要

An optical coupling device, or a compound waveguide (10), in which opticalenergy is coupled to or from an optical signal propagating along atransmitting waveguide is disclosed. The optical coupling device includes athin film organic crystal waveguide (60) positioned in optical proximity to aportion of transmitting waveguide. The organic crystal waveguide (60) has afirst, coupling surface facing the transmitting waveguide through which theoptical energy is coupled. The transmitting waveguide may be a fiber optichaving at least some material removed along a side thereof to facilitate thecoupling of optical energy between the fiber optic and the organic crystalwaveguide. Polishing and lapping methods for producing the thin film organiccrystal waveguide, with optically smooth surfaces, are also disclosed, as areorganic salt implementations of the organic crystal.
