Abstract
Official abstract text for this publication.
An optical semiconductor element includes a ring modulator, and a light absorbing material provided at a position apart from a path for a modulated light which is guided by the ring modulator, the light absorbing material absorbing a light leaked out of a ring waveguide of the ring modulator, and increasing a temperature of the ring waveguide.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical semiconductor element, comprising: a ring modulator; and a light absorbing material provided at a position apart from a path for a modulated light which is guided by the ring modulator, the light absorbing material absorbing a light leaked out of a ring waveguide of the ring modulator, and increasing a temperature of the ring waveguide, wherein a heating value in a first relationship is larger than a heating value in a second relationship at a…
