Photonic topological insulators have emerged as an exciting new platform for backscatter-free waveguiding even in the presence of defects, with applications in robust long-range energy and quantum information transfer, low-threshold lasing, and chiral quantum optics. We demonstrate a design for spin-Hall photonic…

Plasmonic sensors rely on optical resonances in metal nanoparticles and are typically limited by their broad spectral features. This constraint is particularly taxing for optical H2 sensors, in which hydrogen is absorbed inside optically-lossy Pd nanoparticles and for which state-of-the-art detection limits are only at…

A series of new heavy-atom-free photosensitizers using 2,6-diethoxycarbonyl-BODIPY was designed and synthesized. Photoinduced electron transfer between the BODIPY and meso-aryl subunits followed by the formation of BODIPY triplet excited states via spin-orbit charge transfer intersystem crossing (SOCT-ISC) was studied…

Phase change materials (PCMs) with distinct optical properties at different phases are promising candidates for programmable photonics, optical communication and photonic computing. In this work, we have studied thermo-optic effect in a PCM-based integrated photonic device comprising a film of bistable [Fe2Co2]…

The orientation of sensing molecules on the surface of biosensors is crucial for effective interaction with target analytes, and Raman spectroscopy is a versatile and non-invasive technique used to study molecular configurations at the sub-nanoscale level. This study explores the sensing abilities of an integrated…
