Electrically Tunable Propagation Properties of the Liquid Crystal-Filled Terahertz Fiber

open access: yesApplied Sciences, 2018
A bandgap-guiding microstructured fiber for terahertz (THz) radiation was designed by infiltrating the cladding air holes with nematic liquid crystal. Structural parameter dependence of the photonic bandgaps, polarization-dependent bandgap splitting, and

Photoinduced Electron Transfer Based Ion Sensing within an Optical Fiber

open access: yesSensors, 2011
We combine suspended-core microstructured optical fibers with the photoinduced electron transfer (PET) effect to demonstrate a new type of fluorescent optical fiber-dip sensing platform for small volume ion detection.

Highly sensitive salinity sensor based on Mach-Zehnder interferometer with double-C fiber

open access: yesFundamental Research, 2022
This paper proposes a highly sensitive, compact, and low-cost optical fiber salinity sensor based on the Mach-Zehnder interferometer. The sensor is constructed using a single mode fiber (SMF) - no-core fiber - double-C fiber (DCF) - NCF-SMF structure ...

Intrinsically narrowband pair photon generation in microstructured fibres [PDF]

open access: yes, 2011
In this paper we study the tailoring of photon spectral properties generated by four-wave mixing in a birefringent photonic crystal fibre (PCF). The aim is to produce intrinsically narrow-band photons and hence to achieve high non-classical interference ...

Refractive Index Sensing Using Helical Broken-Circular-Symmetry Core Microstructured Optical Fiber

open access: yesSensors, 2022
Helical twist provides an additional degree of freedom for controlling light in optical waveguides, expanding their applications in sensing. In this paper, we propose a helical broken-circular-symmetry core microstructured optical fiber for refractive ...

Index matching between passive and active tellurite glasses for use in microstructured fiber lasers: Erbium doped lanthanum-tellurite glass [PDF]

open access: yes, 2009
Active and passive variants of La-containing tellurite glasses have been developed with matched refractive indices. The consequences of adding lanthanum to the glass was studied through measurements of the crystallization stability, glass viscosity and ...

Design and Dispersion Control of Microstructured Multicore Tellurite Glass Fibers with In-Phase and Out-of-Phase Supermodes

open access: yesPhotonics, 2021
High nonlinearity and transparency in the 1–5 μm spectral range make tellurite glass fibers highly interesting for the development of nonlinear optical devices.
