CLEO 2022: Conference on Lasers and Electro-Optics

With comprehensive, peer-reviewed technical sessions and market-focused programming, CLEO is the world’s premier international forum to learn about innovative advances, research and new technologies from the laser science industry. From quantum computing to advanced imaging technologies used to the search for new life and planets in the galaxy, CLEO brought together all aspects of electro-optic technologies.

CLEO’s world-renowned technical program is a showcase for leading research and applications in a number of fields, from biophotonics to advanced manufacturing, telecommunications, and autonomous vehicles industry, just to name a few. Industry-leading speakers from around the world discuss new scientific ideas and research while the exhibiting companies display the latest innovations in photonics technology.

The 2022 CLEO Conference and Exhibition will be presented as a hybrid event — a combination of in-person and virtual participation options.

Our Chief Quantum Officer Stephanie Simmons will be speaking at the conference about Silicon colour centres.


The future global quantum internet will require high-performance matter-photon interfaces. The highly demanding technological requirements indicate that the matter-photon interfaces currently under study all have potentially unworkable drawbacks, and there is a global race underway to identify the best possible new alternative. For overwhelming commercial and quantum reasons, silicon is the best possible host for such an interface. Silicon is not only the most developed integrated photonics and electronics platform by far, isotopically purified silicon-28 has also set records for quantum lifetimes at both cryogenic and room temperatures [1]. Despite this, the vast majority of research into photon-spin interfaces has notably focused on visible-wavelength colour centres in other materials. In this talk I will introduce a variety of silicon colour centres and discuss their properties in isotopically purified silicon-28. Some of these centres have zero-phonon optical transitions in the telecommunications bands [2], some have long-lived spins in their ground states [3], and some, including the newly rediscovered T centre, have both [4].
