Nano-scale quantum dot optical transducers by self-assembly

We propose a nano-scale optical transducer for future all-optical quantum circuits. The device is comprised of an array of quantum dot islands between opposing electrodes, fabricated by self-assembly. The device operates under low bias and produces a measurable photocurrent in response to light. Mod...

Summary:We propose a nano-scale optical transducer for future all-optical quantum circuits. The device is comprised of an array of quantum dot islands between opposing electrodes, fabricated by self-assembly. The device operates under low bias and produces a measurable photocurrent in response to light. Modeling, fabrication, and preliminary experimental results are presented in this paper.
