We propose a two-colors all-optical gate based on two coupled single-mode Photonic Crystals. Real-time switching and wavelength conversion at a rate up to 10 GHz have been demonstrated.
Silicon photonic crystal nanocavities were monolithically integrated to construct multichannel all-optical switches. Successful operation of 25 resonant channels was demonstrated with a length of only 200 μm and an energy consumption in the femtojoule regime.
Dynamic wavelength switching of a phase-shifted fiber grating cavity with electrical pulses is studied experimentally and numerically. Simulations accurately describe observations. The effect of acoustic oscillations and fiber Bragg grating cavity refilling explains the results.
