Abstract
An improved waveguide polymer electro-optic modulator/switch which is operated in a single mode and has an improved device characteristic compared to the optimized modulator/switch and is capable of enhancing a coupling efficiency with an optical fiber without an increase of the driving voltage, which includes a waveguide formed in one line, a signal electrode formed at an upped input side of the waveguide, to which signal electrode a signal voltage is applied as an upper electrode, and an absorption electrode formed at an upper portion of the waveguide for absorbing a higher order which are not easily absorbed by the signal electrode and for increasing a dissipation ratio.
