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…

BoxCARS and pump-probe geometries are common implementations of two dimensional infrared (2D IR) spectroscopy. BoxCARS is background-free, generally offering greater signal to noise ratio, which enables measuring weak vibrational echo signals. Pulse shapers have been implemented in the pump probe geometry to accelerate…

Luminescent solar concentrators (LSCs) are a promising technology to help integrate solar cells into the built environment, as they are colorful, semi-transparent, and can collect diffuse light. While LSCs have traditionally been cuboidal, in recent years a variety of unconventional geometries have arisen, for example…

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…

We demonstrate a novel approach for bottom-illuminated atomic force microscopy infrared spectroscopy (AFM-IR). This nearfield technique is suitable for AFM-IR measurements in liquids, taking advantage of an attenuated total reflection (ATR) setup where the developing evanescent wave is used for photothermal excitation…

Nonlinear spectroscopies can disentangle spectra that are congested due to inhomogeneous broadening. In conjunction with theoretical calculations, attosecond extreme ultraviolet (XUV) four-wave mixing (FWM) spectroscopy is utilized here to probe the dynamics of autoionizing, inner valence excited Rydberg states of the…

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…

With the increasing demand for optical data transmission and processing by modern communication systems, high-speed optoelectronics operating at telecom wavelengths are greatly desired. Two-dimensional (2D) materials with high carrier mobility and picosecond intrinsic response times exhibit large potential in this…

Coupling of metasurface resonance with a molecular vibration from weak - to - strong is demonstrated using different polymer based materials and metal-insulator-metal (MIM) metasurfaces. It is shown that the strength of coupling between MIM metasurface and molecular absorbance in the I-layer of organic nano-film…
