ABSTRACT:
A sampler that can be used to sample optical or electrical signals, having an improved sensitivity-resolution product compared to conventional samplers. A coded switched electrode modulator has electrodes that produce polarity reversals in an applied voltage signal in accordance with a pseudorandom code having small sidelobes. An optical signal is injected into an optical waveguide that is oriented parallel to the electrodes. When the optical signal is proportional to the coded electrode pattern, the device is used as an electrical sampler. When the applied voltage signal is proportional to the coded electrode pattern, the device is used as an optical sampler.
