Quantum-Compatible Integrated Optoelectronics and Photonics

Dynamically tunable MEMS devices manipulating THz light within a temperature change of 30°C

Recent commercial development has seen the emergence of photonic quantum computers that can operate closer to room temperatures. These quantum computers employ qubits that rely on entangled photon states. In addition, optical addressing of spin and defect-based qubits allow hybrid quantum photonic platforms that route optical control pulses to and from an array of qubits offer an attractive solution to the “fan-out” challenge and the opportunity for direct integration with fiber optic networks for long-range quantum information transmission.

Photonic integrated circuits (PICs) that can implement the required functions can be fabricated at scale by leveraging existing manufacturing infrastructure for electronic ICs. Our team at UD develops device architectures that enable simultaneous electrical and optical interaction with qubits. Team members have expertise in the design, modeling, growth, fabrication, and characterization of semiconductor optoelectronic devices that exploit or control quantum states; active control and high speed modulation in photonic material and device platforms; PIC design, CMOS-integration; and novel metamaterials and optomechanics for control over light propagation and focusing.
