Abstract

New structures for efficient coupling of light from an antiresonant reflecting optical waveguide (ARROW) to integrated photodiode are proposed and analyzed. Both end-fire and leaky-wave types of coupling have been considered and it is found that high-coupling efficiencies can be achieved by exploiting the intrinsic properties of the ARROW structure without requiring additional non-IC compatible materials. The coupling structures were simulated using a simple ray optics model as well as the beam propagation method (BPM). Fabrication process conditions and measurement results for various coupling structures are presented
