Multi-Layered Structures for Low-Temperature Low-Energy Optical Interconnects for Quantum Computers

Connecting quantum computers with the end user is challenging technological problem due to the energy consumption and high data rate requirements. We propose a design of a linearly shaped electrically controlled optical switch based on the studies of propagation of an exciton-polaritons in a quasi-2D, patterned optical microcavity with an embedded semiconducting quantum well. The polaritons are driven by a time-dependent drag force owing to the interaction of neutral or charged excitons (the matter component of polaritons) in a quantum well with the electric current running in the structure. Polaritons are generated due to laser pumping with Gaussian distribution of power in the beam. In our poster, we present our findings and, in particular, we discuss how operating frequency of the electrically controlled optical switch depends on the heterostructure material composition, length of the channel, duration of the drug pulse, and other parameters of the system and estimate the magnitude of such operating frequency.
