A visual tour of the equipment, devices and experimental set-ups behind research in photonics and material science.
Silicon Microspheres for Super-Planckian Light Sources in the Mid Infrared
Silicon microspheres with diameters in the 2–3 micrometre range act as photonic nanocavities. At high temperature, their Mie resonances produce highly selective mid-infrared emission, including modes above the…
Advanced Optical Materials article accepted
Silicon microspheres as compact resonant emitters for super-Planckian light sources in the mid infrared.
Monolayer-to-mesoscale modulation of the optical properties in 2D CrI3
Hyperspectral wide-field imaging reveals a non-monotonic thickness dependence of the complex optical dielectric function in magnetic CrI3, from the mesoscale down to a single layer.
Paper accepted in Physical Review Letters
New work on the monolayer-to-mesoscale modulation of optical properties in magnetic 2D CrI3.
Hermitian and Non-Hermitian Mode Coupling in a Microdisk Resonator
A phase-sensitive study of transmission through a coupled waveguide–microdisk system uncovers asymmetric resonance splitting arising from stochastic roughness and dissipative intermodal coupling.
Unidirectional reflection from an integrated Taiji microresonator
An integrated Taiji-shaped microresonator exploits non-Hermitian dynamics to achieve high-contrast direction-dependent reflection while preserving Lorentz reciprocity in transmission.
Optical properties of organic/inorganic perovskite microcrystals through Fabry–Pérot resonances
A robust method determines the real and imaginary refractive index of MAPbBr3 thin films and microcrystals by fitting optical transmittance and photoluminescence through their Fabry–Pérot resonances.
