Abstract
Multi-channel spatial light modulators are used to excise frequency bands of an RF signal in an optical processing system. An advantage realized in using an optical implementation is the minimal phase distortion introduced into the pass band when a narrow-band notch is implemented. Measured amplitude and phase transfer functions are presented for a 200 MHz bandwidth system with 1 MHz channels.
