Indirect exciton mediated optical transistors

In this contribution, a design for an all-optical excitonic transistor is presented. The purpose of such a device is to perform controlled switching of light using light. This can be achieved using indirect excitons to mediate the interactions between optical signals. Simulations indicate that the design can be successfully implemented in promising new zinc oxide based CQW structures where the high exciton binding energy allows excitonic effects to persist to room temperature.
