Nonlinear Fabry-Perot cavity with chalcogenide glass thin films

open access: yes, 1993
An investigation of a chalcogenide glass thin‐film Fabry–Perot cavity has been performed in picosecond time regime. Nonlinear behavior of the structure derives from both nonlinear absorption of the material and changes in the resonance conditions of the ...

Brillouin–Raman micro‐mapping of silicone‐hydrogel contact lenses: Revealing chemical and mechanical heterogeneities

open access: yesJournal of Microscopy, EarlyView.
Abstract Joint Brillouin–Raman micro‐spectroscopy (BRMS) enables simultaneous, non‐destructive characterisation of the mechanical and chemical properties of soft materials at the micrometre scale, combining GHz‐range viscoelastic information from acoustic modes with the vibrational fingerprint of molecular species.

Wide‐Angle Domain Compatible Flexible Multispectral Stealth Metasurface for Visible Light, Laser, and Microwave

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
A flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...

Optical fiber sensing with a low-finesse Fabry-Perot cavity

open access: yes, 1992
A detailed comparison between a low-finesse Fabry-Perot cavity and a typical two-beam interferometer is developed and checked experimentally. The consequences of approximating the true Fabry-Perot function by the two-beam function are evaluated for ...

Integration of hBN Single‐Photon Emitters Into a Hybrid Optomechanical Membrane‐In‐The‐Middle Fiber‐Cavity

open access: yesNanophotonics, Volume 15, Issue 19, 13 October 2026.
Deterministic manipulation of hexagonal boron nitride (hBN) flakes enables single‐photon emitters (SPEs) to be integrated into a fiber‐based Fabry–Pérot membrane‐in‐the‐middle cavity. Cavity coupling enhances and spectrally funnels the broadband emitter fluorescence, while allowing access to mechanical membrane modes for future hybrid optomechanical ...

Arbitrary Wavefront Manipulation in Real Space and Momentum Space Based on Elliptical Structures

open access: yesNanophotonics, Volume 15, Issue 19, 13 October 2026.
Leveraging elliptical structures—while preserving real space arbitrary wavefront manipulation—we generalize the manipulation to momentum space rather than only sustaining topological singularities. Multifunctional integrated outputs, such as beam deflection and focusing, can be flexibly achieved in the near–infrared communication band, and the ...

Inverse design of compact silicon photonic waveguide reflectors and their application for Fabry–Perot resonators

open access: yesNanophotonics
Silicon photonic waveguide resonators, such as microring resonators, photonic crystal waveguide cavities, and Fabry–Perot resonators based on the distributed Bragg reflectors, are key device components for silicon-based photonic integrated circuits (Si ...
