Reflective-Type High Sensitivity Optical Fiber Hydrogen Sensor Based On Enlar…
Highly sensitive reflective-type fiber hydrogen sensor based on an enlarged taper cascaded with a tilted fiber grating (TFBG) was proposed. Hydrogen-sensitive Au-Pd nanofilm was coated on the TFBG …
A Compact Fluorescent Probe for Real-Time Thermal Monitoring of Chips
In this paper, a compact fluorescent probe based on fluorescence intensity ratio (FIR) technique is proposed for real-time thermal monitoring of chips, the sensing unit of which is based on a self-…
Parametric Amplification and Wavelength Conversion in Dual-Core Highly Nonlin…
In this paper we experimentally show parametric amplification and wavelength conversion in a custom manufactured dual-core highly nonlinear fiber. On-off gain > 10 dB and conversion efficiencies be…
Broadband Ultrasound Detection Using Silicon Micro-Ring Resonators
High sensitivity, broadband bandwidth, small size and scalability to a fine-pitch matrix of ultrasound (US) sensors are essential for high-resolution ultrasonography and photoacoustic tomography. I…
Shell Theory : A Statistical Model of Reality
The foundational assumption of machine learning is that the data under consideration is separable into classes; while intuitively reasonable, separability constraints have proven remarkably difficu…
Low-Light Image and Video Enhancement Using Deep Learning: A Survey
Low-light image enhancement (LLIE) aims at improving the perception or interpretability of an image captured in an environment with poor illumination. Recent advances in this area are dominated by …
Analysis and Compensation of Vibration Induced Beat Frequency Shift in OFDR B…
Optical frequency domain reflectometry (OFDR) is an attractive locating technology for distributed acoustic sensor (DAS) due to its high spatial resolution, but the detectable bandwidth of vibratio…
A Polarization-Insensitive High-Resolution Micro-Spectrometer Using (N + 3) …
Ultra-compact on-chip spectrometers with high resolution and large bandwidth play a crucial role in miniaturized spectroscopic analysis systems. Here we present a novel polarization-insensitive mic…
High-Precision Mode Decomposition for Few-Mode Fibers Based on Multi-Task Dee…
A novel mode decomposition (MD) method based on multi-task learning (MTL) is proposed to obtain high-precision modal weights ( ρn2 ) and modal relative phases ( θn ). Due to the different physica…
Improved Spectral Interrogation of Tilted Fiber Bragg Grating Refractometer U…
This paper proposes a new approach of demodulating the spectra of tilted fiber Bragg grating (TFBG) based refractive-index (RI) sensor by employing convolutional neural networks (CNN) with residual…
