Subpicosecond all-optical logic gate : an application of the optical Stark effect
Résumé
An all-optical logic gate is demonstrated to perform at room temperature with subpicosecond ON and OFF switching time using the same wavelength for both input beams. It consists of a GaAs-GaAlAs multiple quantum well structure inserted in a 1.3 μm thick Fabry-Pérot and uses for its operation a purely optical field effect (optical Stark effect).
