Interested in joining the lab?

The Barclay lab is recruiting undergraduate students and prospective PhD candidates seeking to do research in quantum nanophotonics. We are also seeking postdoctoral researchers with expertise in nanofabrication. If you are interested, please email a brief description of your research interests to Paul, and include a copy of your CV and transcript. Previous nanophotonics experience…

Welcome new lab members!

Welcome to three new lab members: Peyman, who joins us from Tehran, Waleed, who arrives from Queens (where he worked in Stephen Hughes’ quantum photonics theory group), and Natalia, who comes from Campinas (Brazil) with a wealth of optomechanics expertise. Excuse the photo of our alumni. Photos of our new team members are incoming.

Cooling mechanical resonators with a microscope

The lab has harnessed a new type of coupling between light and mechanical resonator to demonstrate a new technique for cooling–removing mechanical energy–from a nanoscale object. This object was fabricated from a diamond chip and was installed in a custom microscope and cryostat designed for combining laser cooling with nanophotonic device measurements. The work was…

Latest publication in Nature Communications

Check out Matt and David’s latest discovery: a technique for interfering light with vastly different different wavelengths. They accomplish this by coupling both optical fields to the same mechanical resonator. The phase of each field affects the motion of the resonator, resulting in an effective interaction between both optical inputs. Two-colour interferometry and switching through…
