Abstract:

The goal of this project is to build a light valve based on a switchable zero order diffraction grating. The grating is made switchable by fabricating it on two facing surfaces and then displacing one surface with respect to the other by half of one period. One way of producing the displacement is to use the strong piezoelectric properties of polyvinylidene fluoride. An alternate scheme using electrostatic forces is also being investigated.
