Measuring the refractive index and thickness of multilayer samples by Fourier domain optical coherence tomography [PDF]
arXivNon-contact measurement of the refractive index and thickness of multilayer biological tissues is of great significance for biomedical applications and can greatly improve medical diagnosis and treatment. In this work, we introduce a theoretical method to simultaneously extract the above information using a Fourier domain optical coherence tomography ...

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices
Advanced Materials Interfaces, EarlyView.This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Advanced Materials Interfaces, EarlyView.Unique nanopillar metasurfaces are fabricated for the purpose of sensitive detection to refractive index changes in the presence of gold nanoparticles. The addition of these nanoparticles to the surface of the silicon nanopillars is facilitated via a novel antibiotic‐mediated linker system to promote localized surface plasmon effects resulting from Mie

Advanced Materials Interfaces, EarlyView.Polyvinyl pyrrolidone passivation enhances TiO2/CsPbI2Br interfaces, suppressing recombination and improving photodetector performance with faster response, higher photoresponsivity, and superior detectivity. Abstract Inorganic perovskites hold immense promise for optoelectronic applications, but their performance is often hindered by defects and trap ...
