Refractive Index and Temperature Sensing Based on Surface Plasmon Resonance and Directional Resonance Coupling in a PCF

open access: yesIEEE Photonics Journal, 2017
We propose a refractive index (RI) and temperature sensor design based on hybrid mechanisms in a D-shaped all-solid photonic crystal fiber. The D-shaped flat surface is coated with a silver film to construct surface plasmon resonance for the RI sensing ...

Thin bonding wires temperature measurement using optical fiber sensors

open access: yes, 2011
In this work we demonstrate the use of optical fiber sensors to measure temperature in thin metallic bonding wires. Temperature was measured in copper wires with diameter of 0.10, 0.28, 0.60 and 0.70 mm and for different values of the driven electrical ...

Design of Environmental Biosensor Based on Photonic Crystal Fiber with Bends Using Finite Element Method [PDF]

open access: yes, 2015
In this paper, a biosensor based on photonic crystal fiber (PCF) is proposed and designed using Full-Vectorial Finite Element Method (FVFEM). The proposed PCF sensor consists of three concentric circles surrounding the core.

A Hollow-Core Photonic Crystal Fiber-Based SPR Sensor With Large Detection Range

open access: yesIEEE Photonics Journal, 2017
We propose a large detection range surface plasmon resonance (SPR) sensor based on hollow-core photonic crystal fiber in this paper. The sensor consists of an analyte channel in the core hole and a silver nanowire in the cladding holes.

Novel layered 2D materials for ultrafast photonics

open access: yesNanophotonics, 2020
A range of new 2D materials have recently been reported, including topological insulators, transition-metal dichalcogenides, black phosphorus, MXenes, and metal-organic frameworks, which have demonstrated high optical nonlinearity and Pauli blocking for ...

A scatterer-assisted whispering-gallery-mode microprobe

open access: yesNanophotonics, 2018
A fiber-based whispering-gallery-mode (WGM) microprobe, combining both the high optical field enhancement of the WGMs and the compact structure of the optical fiber, is highly desired for sensing and imaging.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Extremely High-Efficiency Coupling Method for Hollow-Core Photonic Crystal Fiber

open access: yesIEEE Photonics Journal, 2017
We report a novel low-loss splicing approach for hollow-core photonic crystal fiber (HC-PCF) and conventional single mode fiber (SMF) by inserting an etched SMF tip into the hollow core.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

New multiplexing scheme for monitoring fiber optic Bragg grating sensors in the coherence domain

open access: yes, 1997
A new multiplexing scheme for monitoring fiber optic Bragg gratings in the coherence domain has been developed. Grating pairs with different grating distances are distributed along a fiber line, and interference between their reflections is monitored ...
