Abstract

Some of the remarkable properties of excitonic transitions in QW structures as they pertain to devices that can make an impact on optical computing are examined. An MQW-HBT device is discussed where the large built-in gain in the device as well as the ability to control the device response optically or electronically provides a versatile building-block device. Applications of this device to thresholding switching, light ''amplification'', and programmable memory are considered, and the wavelength selective properties of excitonic detectors are explored.
