Class Information
Number: 385/41
Name: Optical waveguides > With optical coupler > Particular coupling structure > Electrodes on or near the coupling region > Directional coupler
Description: Subject matter wherein interconnected optical paths of a coupler are externally activated to enable input on a first optical path to be coupled only to a second optical path for optical beam transmission, and a received optical beam on a third optical path is coupled only to the first optical path.
