ABSTRACT:
A waveguide-type optical device of the invention has a dielectric substrate, wave-guiding paths formed in the dielectric substrate, and electrodes for forming an operation-controlling electric field for the wave-guiding paths. A carrier capture layer is provided in a region into which carriers are injected from at least one of the electrodes.
