ABSTRACT:
An optical subassembly is disclosed which provides self-alignment between an active optical device and associated optical elements. In particular, the subassembly comprises a first substrate member which is utilized to support the active optical device. A separate plurality of substrate members is used to form a support for the associated optical elements (i.e., fiber, coupling lens or both), where the separate members are stacked, one on top of the other, and an aperture through the center thereof utilized to support the optical elements. The aperture may be formed to include a mechanical stop suitable for fixing the location of an optical fiber endface. Alignment fiducials formed on the device support member and the stack provide self-alignment therebetween, as well as physical attachment of the support member to the stack. The various substrate members may comprise any suitable material including, but not limited to, silicon, metal, or molded plastic.
