A high-performance electrooptic intensity modulator using polymeric waveguides utilizes and a dumping effect and high-efficiency modulation process is implemented by a grating modulation. These two waveguides can be either single-mode or multi-mode, even highly multimode. In accordence with theoretical study, the total coupling efficiency between two waveguides can not be achieved a high value for both single- and multi- mode waveguides. The introduction of a modulated grating-dumping wall on the outside edge of a channel makes the coupling between two waveguides become unidirectional and the coupling efficiency can be achieved to be approximately 100% in theory. Furthermore, a high-efficiency electro-optic intensity modulator is implemented. These two waveguide channels in this intensity modulator may have large dimensions, so this device can support either low or high power operation. Thereby this electro-optic intensity modulator is called high performance modulator and can be developed into either a single optical switch or a waveguide switch array of optical cross-connect for fiber- optic communication.
