- The results presented here demonstrate the viability of using a Barium Titanate - film on silicon and silicon nitride photonic devices to achieve ultra-fast optical switching at cryogenic temperatures. This is possible using the Pockels effect, reducing power consumption in such devices to near-zero, allowing a scalable approach to large complex integrated photonic circuits operating at cryogenic temperatures. This enables the long-term plan of combining an integrated photonic platform with detectors and modulators for quantum information processing applications. The work was a collaboration between a team at IBM, and Bristol a collaboration initially established by prof. Mark Thompson.
