In-line polymeric construct for modulators, filters, switches and other electro-optic devices

An in-line electro-optic construct, comprising:

• (a) a substrate base, said substrate base having a surface;
• (b) a optical fiber extending arcuately through said substrate base, said optical fiber comprising an inner core surrounded by outer cladding;
• (c) an evanescent coupling region wherein said outer cladding is removed between said inner core and said surface of said substrate base;
• (d) at least two coplanar electrodes deposited on said surface of said substrate that are spaced apart by a gap aligned over said evanescent coupling region;
• and
• (e) a compliant electro-optic waveguide overlaying said electrodes.

A coplanar waveguide polymeric in-line electro-optic construct, comprising:

• (a) a substrate base, said substrate base having top and bottom surfaces and first and second ends;
• (b) a single mode optical fiber embedded in said substrate base and extending arcuately between said first and second ends, said optical fiber having an inner core surrounded covered by outer cladding;
• (c) first and second co-planar electrodes on said top surface of said substrate, said electrodes spaced-apart by a gap, said electrodes forming a transmission line;
• and
• (d) a multimode waveguide overlaying said electrodes, said waveguide comprising an electro-optic polymer material having an index of refraction that is controlled by said electrodes, wherein said top surface of said substrate is polished down through said outer cladding of said optical fiber proximate to said inner core so as to form a coupling region, wherein said electrode gap is aligned over said coupling region, and wherein light transmitted through said optical fiber is evanescently coupled to said waveguide thorough said coupling region.
