Abstract
The invention relates to an optical integrated circuit microbench system for accurately aligning optical fiber and waveguides to efficiently couple energy between optical devices. This is accomplished by using the anisotropic etch characteristics of III-V semiconductor materials in two orthogonal directions. One etch direction serves to provide a channel for precise fiber-positioning; the other direction, which is orthogonal provides a reflecting surface for directing the optical energy onto optical devices.
