要約
(EN)
An optical transmitter has: a ring waveguide; electrodes, which are formed in the vicinity of the ring waveguide, and which have signals applied thereto; a first waveguide, which is optically coupled to the ring waveguide; a second waveguide, which is optically coupled to the ring waveguide without being optically coupled to the first waveguide directly; and a light source, which supplies continuous light to the first waveguide.
