| Abstract(in English) | We have proposed a Si hybrid MOS structure where a thin III-V semiconductor membrane is bonded on a Si waveguide with a gate dielectric for optical modulators. Electron accumulation at the III-V MOS interface induced by an application of a gate voltage enables us to use the electron-induced refractive index change in the III-V semiconductor. As a result, we have successfully achieved efficient low-loss optical phase modulation. The phase modulation efficiency is 0.05 Vcm, which is approximately 10 times better than that of a depletion-based Si optical modulator. Moreover, The optical loss accompanying with phase modulation is 10 times smaller than that of a Si optical modulator, improving optical modulation amplitude significantly. We discuss the potential of a Si hybrid MOS optical modulator beyond 100 Gbps application. |
