Our recent work on ‘Observation of nonvanishing optical helicity in thermal radiation from symmetry-broken metasurfaces’ has been published in Science Advances. We uncover a new method for generating spinning thermal radiation in a controlled & efficient manner using metasurfaces. Spinning thermal...

In this talk, Dr. Chen-Ting Liao introduced the topology of light – the light carrying orbital angular momentum (OAM). The OAM of light can be static, dynamic, or spatiotemporal. Static OAM of light has been known for three decades and has found numerous applications, from optical trapping, and...

Our latest research on a new class of quantum detectors is published in New Journal of Physics. Here, we propose the "photon discerner", a device which uses adaptive photon thresholding for photon statistical estimation without recording exact photon numbers. We show that the adaptivity of our...
