An integrated cryogenic optical modulator

Understand

Integrated electrical and photonic circuits (PIC) operating at cryogenic temperatures are fundamental building blocks required to achieve scalable quantum computing, and cryogenic computing technologies.

• Optical interconnects offer better performance and thermal insulation than electrical wires and are imperative for true quantum communication.
• Silicon PICs have matured for room temperature applications but their cryogenic performance is limited by the absence of efficient low temperature electro-optic (EO) modulation.
• While detectors and lasers perform better at low temperature, cryogenic optical switching remains an unsolved challenge.
