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…
