Cooling mechanical resonators with a microscope

Laser cooling a mechanical resonator 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…

Undergraduate Student Opportunities

Undergraduate Student Opportunities Our lab regularly employs undergraduates for both paid research assistantships (typically during the summer, often with help from NSERC USRA funding) as well as senior thesis project (PHYS 598).   Undergraduates interested in projects related to experimental, computational, or theoretical aspects of nanophotonics and quantum optics are encouraged to email Prof. Paul Barclay.…

Silicon Photonic Spin-Optomechanical Sensors

Silicon Photonic Spin-Optomechanical Sensors We have recently demontrated nanocavity optomechanical devices based on silicon photonics which can detect sources of torque with unprecedented sensitivity. These structures are currently being used toprobe nanomagnetic phenomena and demomstrate magnetic field sensors with unique combination of spatial resolution, sensitivity and dynamic range. Several projects are building on this success: creating sensors for…

2D Material Based Nanophotonics and Optomechanics

2D Material Based Nanophotonics and Optomechanics 2D materials, the most famous of which is graphene, are promising for sensing and quantum technology. Hexagonal boron nitride (hBN) is a layered 2D material that is exciting thanks to its ability to host quantum emitters / single photon sources. By combining hBN with silicon photonic devices, we recently…

Nonlinear Optics

Nonlinear Optics Thanks to its large electronic bandgap, GaP is one few semiconductors which is transparent at both visible and telecom wavelengths. This makes it a promising material for nonlinear and quantum optics applications involving frequency and photon pair conversion. These experiments are on-going, and have the potential to result in highly-efficient chip-based sources of…
