Paper Abstract

Single-mode optical D-fiber is fabricated and coupled to a buried polymer acrylic waveguide by a novel technique with a transcision and alignment ways. The D-fiber is fabricated by lapping the cladding layer of a single-mode fiber to the core. Optical waveguides and alignment ways are made with polymers by photodefinition. This technique combines the optical elements with a transcision placed perpendicular to the optical axis of the waveguide to offer an efficient coupling of single- mode fiber to optical waveguide with an excess coupling loss of 0.25 dB. This coupling loss is found using a cutback experiment and buried polymeracrylic waveguides. Also, this coupling technique has been used to achieve excess passive-coupling losses of 0.9 dB.
