Underwater Acoustic Wave Detection Based on Packaged Optical Microbubble Reso…
We demonstrate an optical underwater acoustic sensor with high sensitivity and broad bandwidth (10 Hz to 100 kHz), based on the packaged optical microbubble whispering gallery mode resonator, for t…
Research on 3D Optical Module Integrating Edge Coupler and TSV
3D integration photonic interposer is becoming popular in the field of co-packaging optics (CPO). In this paper, we integrate the edge coupler and through silicon via (TSV) into the silicon interpo…
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 Contribution to the Development of High-Voltage dc Circuit Breaker Technolo…
To promote the integration of renewable energy resources into modern energy systems, high-voltage dc (HVdc) and circuit breaker (CB) technologies have become critical to achieving secure and effici…
Design of a Mach-Zehnder Interferometric Fiber Sensing System Based on PCA-As…
We propose and numerically design a Mach-Zehnder interferometric sensing system using principal-component-analysis-based orbital angular momentum (OAM) interrogation for simultaneous measurement of…
Using Data Pre-Processing and Convolutional Neural Network (CNN) to Mitigate …
New systems and technologies, such as Internet-of-Things (IOT) may require high reliability and high accuracy indoor positioning and tracking of persons and devices in indoor areas. Among different…
Spectral and Repetition Rate Programmable Fiber Laser
We have demonstrated a spectral and repetition rate programmable Yb-doped fiber laser (YDFL) employing an acousto-optic tunable filter (AOTF) as both the intra-cavity spectral filter and temporal m…
NLM Parameter Optimization for φ-OTDR Signal
The filtering parameters of non-local means (NLM) that seriously affect the denoising results are usually optimized based on the noise level estimation. But the noise level is unknown in many cases…
Integration Time and Time-Bin Width in Ranging Histograms for a Photon-Counti…
High-performance light detection and ranging (LiDAR) modules are highly demanded for advanced driving assistance system and autonomous driving. With CMOS-fabricated single-photon avalanche diodes (…
Extraction of AMCC Signal Superposed by SOA-Integrated EA-DFB Laser for In-Se…
We propose an in-line monitoring method that enables fully passive extraction of the control signal for end-to-end optical direct connection on the All-Photonics Network (APN), which is one of the …
