Abstract
Liquid crystal devices are described that maintain performance of polarization/amplitude modulation under high irradiance conditions. Configurations that isolate polarizing elements under high thermal load are discussed which allow other elements, such as glass, which may be sensitive to stress birefringence to remain near optimum thermal conditions.

1-22. (canceled)
A polarization switch, comprising:
- a first assembly operable to receive light, comprising:
- a first end cap;
- a first polarizer located to receive light from the first end cap;
- a second end cap located to receive light from the first polarizer;
- a second assembly located to receive light from the first assembly, comprising:
- a third end cap;
- a first cell located to receive light from the third end cap;
- a second cell located to receive light from the first cell;
- a fourth end cap located to receive light from the second cell;
- wherein an air gap separates the first assembly from the second assembly.
