Abstract
Various designs of optical switch are disclosed. In one embodiment, the optical switch uses wedges to hold up a collimator and secure the wedges and collimator to a substrate with a type of adhesive, thus avoiding high temperature in soldering process. There are at least two assemblies bonded to the substrate using the adhesive. Each of the assemblies includes a collimator and two wedges, where the wedges are provided to physically hold up the collimator in position. The assemblies are glued directly to the substrate after an optical alignment is performed.
