Reconfigurable all-diffractive optical filters using phase-only spatial light modulators
, 2010 We demonstrate a reconfigurable optical filter implemented using a phase-only two-dimensional liquid crystal on silicon spatial light modulator. To achieve this we utilize two different approaches leading to two different configurations in the modulator.
