Ultrafast non-inverting wavelength conversion by cross-absorption modulation in silicon wire waveguides

Ultrafast non-inverting wavelength conversion by cross-absorption modulation in silicon wire waveguides

We demonstrate all-optical wavelength conversion by means of cross absorption effect induced by two photon absorption (TPA) in submicron sized Si wire waveguides. Optical pulses of 1.6 ps at 1 GHz repetition rate were successfully converted from 1550 nm to 1532 nm. We discuss the performance at high...

Zusammenfassung:We demonstrate all-optical wavelength conversion by means of cross absorption effect induced by two photon absorption (TPA) in submicron sized Si wire waveguides. Optical pulses of 1.6 ps at 1 GHz repetition rate were successfully converted from 1550 nm to 1532 nm. We discuss the performance at higher speed. Our results showed that silicon waveguides have potential applications in high speed photonic signal processing.
