Optical fiber magnetic field sensor based on magnetic fluid and microfiber mode interferometer
(2014)
A magnetic field sensor is proposed based on the combination of magnetic fluid (MF) and an optical microfiber mode interferometer (MMI). It is measured that the MMI is highly sensitive to ambient refractive index (RI) with ...
Cascaded fiber-optic Fabry-Perot interferometers with Vernier effect for highly sensitive measurement of axial strain and magnetic field
(2014)
We report a highly sensitive fiber-optic sensor based on two cascaded intrinsic fiber Fabry-Perot interferometers (IFFPIs). The cascaded IFFPIs have different free spectral ranges (FSRs) and are formed by a short section ...
Improved location algorithm for multiple intrusions in distributed Sagnac fiber sensing system
(2014)
An improved algorithm named “twice-FFT” for multi-point intrusion location in distributed Sagnac sensing system is proposed and demonstrated. To find the null-frequencies more accurately and efficiently, a second FFT is ...
Design of plasmonic nanopore platforms for single-molecule detection
(2014)
In this letter, we proposed and numerically demonstrated a novel plasmonic nanopore platform for single-molecule detection. Bowtie nanoantennas and photonic cavities were studied to obtain Raman enhancement at single-molecule ...
Magnetic field sensor with optical fiber bitaper-based interferometer coated by magnetic fluid
(2014)
An optical fiber magnetic field sensor is demonstrated using a waist-enlarged fusion bitaper-based optical fiber Mach-Zehnder interferometer (MZI) coated by magnetic fluid (MF). Since refractive index (RI) of the MF is ...
Efficient phase-matched third harmonic generation in an asymmetric plasmonic slot waveguide
(2014)
An asymmetric plasmonic slot waveguide (APSW) for efficient phase-matched third harmonic generation (THG) is proposed and demonstrated theoretically. Nonlinear organic material DDMEBT polymer is integrated into the bottom ...
Magnetic field sensor based on reflection spectrum measurement of fiber Bragg grating
(2014)
A novel magnetic field sensor by using an optical fiber Bragg grating (FBG) cascaded by a cleaved optical fiber end, which is face surrounded with magnetic fluid (MF), is experimentally demonstrated. Through Fresnel ...
Highly sensitive refractive index sensor based on two cascaded microfiber knots with vernier effect
(2014)
A highly sensitive refractive index (RI) sensor based on two cascaded microfiber knots with vernier effect is proposed and demonstrated by theoretical arithmetic. Deriving from high proportional evanescent field of microfiber ...
Design and fabrication of a holey fiber microfluidic device with transverse micro-channel
(2014)
In this report, we present a design of holey fiber structure with six air holes in the cladding and a transverse microfluidic channel intersecting the silica core for liquid detection purpose. The simulation results suggest ...
Programmable multi-wavelength filter with Mach–Zehnder interferometer embedded in ethanol filled photonic crystal fiber
(2014)
We experimentally demonstrated a free spectrum range (FSR) tunable comb filter based on a programmable thermo-controlled Mach–Zehnder interferometer. The device is constructed by sandwiching a length of ethanol-filled ...
