ABSTRACT:
The attenuation from connectors to the interaction region of the light signal with the microwave can be reduced, and the bandwidth can be improved in an optical waveguide device, in which a space between strip lines on a ceramic substrate at one end of the strip lines connected to first and second input sections is adapted to be narrower than a space between the strip lines at the other end of the strip lines connected to first and second electric connectors.
