Abstract
The invention relates to an optical integrated alignment device 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. One orthogonal etch direction serves to provide a channel for precise fiber-positioning; the other direction, which is also orthogonal provides a reflecting surface for directing the optical energy between optical devices; and finally, a non-selective etch to form a micro-optical lens to focus optical energy to an optical device.
