Fiber-interface directional coupler inscribed by femtosecond laser for refractive index measurements

Jiangtao Zhou, Zhechen Zhang, Yiping Wang, Jiachen Wang

A novel fiber-interface directional waveguide coupler was inscribed on the surface of a coreless fiber by femtosecond laser, and was successfully applied to highly sensitive refractive index (RI) measurements. The primary arm was first inscribed to couple ...

Recent Advances in Resonant Waveguide Gratings

Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, Guillaume Basset

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide-mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes from UV to microwave freq ...

Hatice Altug, Andreas Tittl, Aurélian Michel John-Herpin, Daniel Rodrigo Lopez, Odeta Limaj

Tailoring nanoscale light concentration and electromagnetic near-field enhancement over a broad spectral range is crucial for many photonics applications such as infrared spectroscopy, photodetection, and light harvesting. So far, broadband light enhanceme ...

Discrimination of temperature and strain by combined refractive index and birefringence measurements using coherent Rayleigh sensing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

Temperature and strain discrimination is experimentally demonstrated in an elliptical-core polarization-maintaining fiber by making use of Rayleigh-based distributed birefringence measurements and the frequency shift of the correlation peak obtained by sta ...

Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes

Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire

Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...

Volume refractometry of liquids using stable optofluidic Fabry-Perot resonator with curved surfaces

Maurine Malak Karam Awadallah

This work reports a simple, miniaturized optical sensing module for liquid refractometry. It is based on a stable Fabry-Perot resonator consisting of two silicon cylindrical mirrors with a cylindrical lens in the core. The lens is formed by a capillary tub ...

New diagnostics for density measurement on Frascati Tokamak upgrade

Fabio Avino, Anton Petrov

In FTU, density profile is measured with two new diagnostics: a CO2/CO scanning interferometer and a time-of-flight radar (denominated refractometer). The first, using two scanning beams, can provide a plasma density profile every 62.5 mu s. Two lasers (CO ...

Refractive index sensor based on slot waveguide cavity

Hans Peter Herzig, Qing Tan, Armando Cosentino

The experimental study of a gold slot waveguide cavity is presented. The resonance of this cavity working in the telecom wavelength range is highly dependent on the refractive index of the medium located in or around the slots array, because of the high co ...
