All-optical switching in a normally-off asymmetric Fabry-Perot etalon is reported. The switching action is based on optically induced absorption and refractive index changes in a GaAs-AlGaAs multiple quantum well. A high switching contrast ratio with a very low associated insertion loss is obtained.
