Optical intensity-to-phase converter, mach-zehnder interferometer, optical A/D converter, and method of constructing optical intensity-to-phase converter

摘要

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.

主权项

1. An optical intensity-to-phase converter comprising:
first and second waveguides, a first input light being input to the first and second waveguides; a third waveguide, a second input light being input to the third waveguide; a first interaction region that is provided in common on the second and third waveguides, the first and second input lights being multiplexed and interacting in the interaction region; and a second interaction region that is provided on the first waveguide, with the same size as that of the first interaction region, the first input light being input to the second interaction region and the second input light not being input to the second interaction region, wherein 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.
