Abstract

According to one embodiment, a micro-optical device includes an electro-optical circuit and an annular frame disposed on a surface of a substrate. The electro-optical circuit has an active region that is encapsulated by a window and an interconnect region adjacent at least one edge of the electro-optical circuit. The annular frame extends around an outer periphery of the window and is separated from the window by a gap, the annular frame and the electro-optical circuit form a cavity for placement of a plurality of bonding wires the interconnect that electro-optical circuit to the substrate.
