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
Ultrafast all-optical switching by use of pulse trapping in birefringent optical fiber is demonstrated both experimentally and numerically. The wavelengths of the control soliton pulse and the trapped soliton pulse are shifted to satisfy the condition of group velocity matching. Furthermore, the energy...
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...
reaching consequences: the first lead‐iodide‐based ultrafast photonic device and resonantly confined electromagnetic field tailored transient nonequilibrium dynamics of PbI2 which could also be applied to a broad range of semiconductors for designing on‐chip, ultrafast, all‐optical switchable photonic ...
That will require ultrafast technologies for processing optical signals in the form of light, without intermediate transformation to electrical signal processing. A key device of such systems will be ultrafast all-optical switching that can control the intensity of optical signals in an appropriate ...

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...
An all-optical switch would use light to control optical signals without the need for electrical conversion, saving time and energy in fiber optic communications. “Because a switch is the most elementary building block of any information processing unit, an all-optical switch is the first step ...
University of Arizona assistant professor of physics and optical sciences Mohammed Hassan and collaborators devised all-optical switching of a light signal on and off to reach data transfer speeds exceeding a petahertz, measured at the attosecond timescale. The method introduced in the work can be ...
An ultrafast all-optical nonlinear switch. The switch has as components a substrate and a material disposed on the substrate. In one embodiment, the material includes a p
