REINFORCED MULTI-BODY OPTICAL DEVICES

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.

1. A method for fabricating a reinforced multi-body optical device, the method comprising:
applying a coating to either side of an interior plate; a first bonding, using heat and pressure, bonding two plates to either side of the interior plate; dicing the bonded plates at an angle that is not orthogonal to the bonded plates; removing top and bottom portions of a diced section to form a multi-body polarization beam splitter (PBS) having a generally rectangular perimeter; a second bonding, using heat and pressure, bonding a supporting plate 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; and grinding the multi-body PBS to reduce the thickness of the multi-body PBS.
