In this paper we consider some features of all-optical switching in a unidirectional ring cavity which is partially filled with a fast and saturably nonlinear medium. A comparative study of cross-talk for both signs of nonlinearity, in a two pixel (whole-beam switching) configuration, is made...

The nonlinear, all-optical switching characteristics of a GaAs-based directional coupler are investigated. The structure consists of two Al0.18Ga0.82As planar waveguides coupled through a GaAs–AlGaAs multiple quantum well (MQW) layer. Changing the refractive index of the MQW layer, through a Kerr-...
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
Optical nonlinear functions are crucial for various applications in integrated photonics, including all-optical information processing1, photonic neural networks2,3 and on-chip ultrafast light sources4,5. However, the weak native nonlinearity of most nan

Covering all aspects of optical switching, this book focuses on the mechanisms at the core of all-optical switching. It first introduces different types of switching mechanisms then describes all-optical switching using optical switches controlled with light. Areas covered include all-optical switching ...
Single-photon all-optical switching using coupled microring resonators - Yang, Joshi, et al. - 2007 () Citation Context ...d may exhibit a tradeoff for linear properties [6]. For example, the nonlinear effects can also be used to realize bistability engineering for all-optical switching, and...

We demonstrate all-optical modulation of individual resonances of a two-ring silicon microresonator switching fabric using Raman-induced loss. The number of unique output states for such a switching fabric scales exponentially with the number of signals. Published in: Lasers and Electro-Optics (CLEO)...
