Abstract
An integrated sensor and optical phase/amplitude modulator device including a modulator stacked on or above a detector. A circuit receives a signal outputted from the detector in response to an input field irradiating the detector. The circuit performs binary operations comprising classifying the input phase of the input electromagnetic radiation into one of two ranges and setting the modulator into one of two states depending on which range the input phase is classified into. The modulator transmits output electromagnetic radiation having an output field modulated according to the state of the modulator set by the circuit.
