A Refractive Index Sensor Based on PCF With Ultra-Wide Detection Range

IEEE Journal of Selected Topics in Quantum Electronics, 2021
An ultra-wide detection range refractive-index sensor based on surface plasmon resonance (SPR) with photonic crystal fiber (PCF) is designed and discussed. The central air-hole of the fiber is injected with the analyte. The properties of refractive-index

Refractive index of different perovskite materials

Journal of Materials Research, 2021
The perovskite solar cell technologies are the hope of satisfying the huge demand of tomorrow’s energy requirements. The inorganic, organic and mixed perovskite materials are the backbone of modern solar cells. The energy band gap and refractive index of

Optical Refractive Index Sensors with Plasmonic and Photonic Structures: Promising and Inconvenient Truth

Advanced Optical Materials, 2019
Optical sensors are widely used for refractive index measurement in chemical, biomedical, and food processing industries. Due to specific field distribution of the resonances, optical sensors provide high sensitivity to ambient refractive index ...

Microchannel-based plasmonic refractive index sensor for low refractive index detection.

Applied Optics, 2019
A microchannel incorporated photonic crystal fiber (PCF)-based surface plasmon resonance (SPR) sensor for detection of low refractive index (RI) at near-infrared wavelength is presented in this paper. To attain a simple and practically feasible mechanism,

Exposure-dependent refractive index of Nanoscribe IP-Dip photoresist layers.

Optics Letters, 2019
The refractive indices of photoresists used for direct laser writing (DLW) have been determined after exposure to ultraviolet (UV) light. However, it was anticipated that the refractive index will differ when applying a two-photon polymerization (TPP ...

Realization of ultrahigh refractive index in terahertz region by multiple layers coupled metal ring metamaterials

Journal Electromagnetic Waves and Applications, 2019
We report a polarization-independent unnaturally high refractive index metamaterial. It is found that the effective permittivity of the designed metamaterial can be drastically increased by the capacitive coupling effect. Also, the effective permeability

Refractive Index Measurement of High Refractive Index Glass Beads

Applied Optics, 1975
The refractive index of a small sphere and rod was measured by a method using the theory of rainbow that the minimum deviation angle of a single internally reflected ray from a sphere depends solely on the relative refractive index of the sample to the medium. Experimental results confirmed an accuracy of about 1%. This method is particularly suited to
