Abstract:
1. A micro-optical device comprising: a digital micro-mirror device disposed on a surface of a substrate, the digital micro-mirror device having an active region that is encapsulated by a window and an interconnect region adjacent at least one edge of the digital micro-mirror device; a plurality of bonding wires that electrically couple the interconnect region to the surface of the substrate; and an annular frame attached to the surface and extending around an outer periphery of the window, the annular frame separated from the window by a gap that is less than 1000 microns in width, the annular frame and the digital micro-mirror device forming a cavity for placement of the plurality of bonding wires, the annular frame having a height approximately the same height as the window from the surface of the substrate and having an outer surface configured with one or more mechanical alignment features that are operable to couple an optical device to the electro-optical circuit at a predetermined position and orientation.
