Experimental study demonstrates room-temperature optical bistability at 488 nm in a ZnSe/ZnCdSe quantum well device, highlighting viability for blue-green optical switches.
Optical bistability at room temperature has been observed for the first time in a II-VI semiconductor self-electro-optic effect device fabricated by molecular beam epitaxy. The optical switch is based on a ZnSe/ZnCdSe multiple quantum well structure situated within a p-n junction and the devices operate at 488 nm in the blue-green spectral region.
