  • In-line polymeric construct for modulators, filters, switches and other electro-optic devices
    Patent number: 6047095
    Abstract: A coplanar waveguide polymeric in-line fiber construct (CPW-PILF) formed on an optic half coupler substrate base or D-fiber wherein the surface is polished down through the cladding on the optical fiber so as to form an evanescent coupling region on the surface. Co-planar, spaced-apart electrodes are deposited on the surface with their gap aligned over the coupling region, and an electro-optic (EO) polymeric waveguide is deposited over the electrodes and between the electrode gap. Light transmitted thorough the optical fiber is evanescently coupled to said waveguide and modulated by a signal applied to the electrodes. Alternatively, the waveguide is deposited on the surface of the substrate and the electrodes are deposited over the waveguide.
