Abstract
An optical intensity-to-phase converter according to the present invention includes first and second waveguides to which a first input light is input, a third waveguide to which a second input light is input, and an interaction region that is provided in common on the second and third waveguides in which the first and second input lights are multiplexed and interact. The optical intensity-to-phase converter provides delay to output lights output from the first and second waveguides based on intensity of the first or second input light. Then, it is possible to provide an optical intensity-to-phase converter that enables simple configuration of an optical A/D converter.
