ABSTRACT:
The invention relates to a fixed gap waveguide taper. The waveguide taper has a first end and a second end for being coupled to a fiber. The waveguide taper includes a plurality of segments extending from the first end toward the second end. The segments include a gap portion and a core portion. In the present invention, the gap portion remains fixed at a constant length s throughout the entire waveguide taper. In contrast, the core section of the segment varies from the waveguide end of the taper toward the fiber end of the taper. In particular, the core section in each of the segments progressively decreases in length from the waveguide end toward the fiber end of the taper. Accordingly, the length of the segment .LAMBDA. progressively decreases from the waveguide end toward the fiber end of the taper.
