Michela Picardi

Michela Picardi is a PhD student contributor to Physics World. Michela is a PhD candidate in the photonics and nanotechnology research group at King’s College London, under the supervision of Francisco Rodriguéz-Fortuño. Her research interests are in the theoretical and experimental exploration of the degrees of freedom of light and their mutual interaction. “Spin and orbital angular momenta of light”, “electric and magnetic dipole” and “unidirectional coupling” are the three phrases that you would most likely hear from her on a weekday. The fourth would probably be “Give me some pizza, please.”

Unveiling the topological nature of electromagnetic surface waves

Predicting the number of surface modes and their polarization may be possible from the helicity operator, according to a recent study

Dielectric nano bowties allow ultrahigh light confinement

The strong field enhancement and subwavelength resolution in these fully dielectric structures are potentially comparable to plasmonic nanostructures but promise ultralow losses

Lasing on the edge

Topological insulator lasers achieve high efficiency and single-mode lasing at high gains

Chiral metamaterial enables scatter-free propagation

Novel design enables first experimental observation of topological behaviour in a microwave metamaterial
