摘要： A reinforced multi-body optical device that in one embodiment includes a multi-body optical device having a thickness that is less than or equal to about 1.0 millimeter and a supporting plate bonded without epoxy to the multi-body optical device. In an embodiment the supporting plate has a coefficient of thermal expansion (CTE) that is within about 0.5 parts per million of the CTE of the multi-body optical device.

摘要： Disclosed in one example embodiment is a method for fabricating a reinforced multi-body optical device. One method involves applying a coating to sides of an interior plate and bonding two plates to either side of the interior plate. The bonded plates are diced at an angle that is not orthogonal to the bonded plates. The top and bottom portions of a diced section are removed to form a multi-body polarization beam splitter (PBS) having a generally rectangular perimeter. A supporting plate is bonded to the multi-body PBS to form a reinforced multi-body PBS, wherein the supporting plate has a CTE that is within about 0.5 parts per million of the CTE of the multi-body PBS. The multi-body PBS is grinded to reduce the thickness of the multi-body PBS.
