Abstract

We describe the series of all-optical circuit elements that have arisen by exploitation of very large third order non-linearity which has been discovered near the band gaps of III–V semiconductors. The biggest effects are found in InSb and CdxHg1-xTe. Electron excitation from a broadened band tail is held to be responsible in some cases and may therefore be expected in the case of amorphous materials. Numerous device possibilities exist.
