Abstract:
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.
