Paper Abstract

As an extension of an existing electron beam deflector, an optical analog-to-digital (A/D) conversion scheme is presented. As a fast theta modulator, a wide-band acousto-optic (A-O) deflector that performs a voltage to optical beam deflection angle mapping is used. Using a GaP A-O deflector, a proof-of-principle 6-bit A/D converter is experimentally demonstrated.
