Fig. 1: Ultrafast all-optical switching modulation concept. Full size image To prove the ENZ nature of our system, we first characterized the steady-state spectral response in terms of absoluteRas a function of the angle of incidenceθand of the incident light wavelengthλ. In Fig.2 a, bwe...
All-optical switches have attracted attention because they can potentially overcome the speed limitation of electric switches. However, ultrafast, energy-efficient all-optical switches have been challenging to realize owing to the intrinsically small opt
This means that a substantial improvement in the speed of a communication or computing system can be achieved if basic logic operations and signal routing is performed in the optical stage, by means of optically controlled devices with sub-picosecond switching times. As a consequence, much research...

Lastly, we test simple linear devices such as bends, directional couplers, and Sagnac interferometers. From our observations of the nonlinear optical properties in bulk samples and our demonstration of basic on-chip devices, we conclude that TiO2 is a viable material for all-optical applications....
An integrated Y-junction switch is used to demonstrate all-optical switching due to two mechanisms in GaAs-AlGaAs multiple quantum well structures at room temperature. Carrier-induced nonlinearities are compared to nonlinearities due to the optical Stark effect for ultrafast operation. In the first cas...
In this Letter, we report for the first time to our knowledge that all-optical switching gain can be achieved with a dual-wavelength control versus pump beam scheme in a single semiconductor waveguide structure. That means a weak optical beam can switch a strong optical beam. Moreover, a hig...
