Abstract

We demonstrate efficient nonlinear functions using silicon nanophotonic structures. In the ultrasmall core of the waveguides and cavities, nonlinear phenomena are significantly enhanced. Applying the two-photon absorption effect, we have confirmed all optical modulation, in which the modulation speed is improved to around 50 ps by eliminating free carriers. Applying the four-wave-mixing effect, we have achieved high-efficiency wavelength conversion. The conversion efficiency is -11 dB, and the efficiency will be further improved by eliminating free carriers. Using the fourwave-mixing effect, we have also realized a low-noise entangled photon pair source. The source does not need a refrigeration system for noise reduction, which is a great advantage for practical application.
