Fabrication of Polymer Optical Waveguides by Digital Ultraviolet Lithography
We present the design, fabrication and characterization of polymer optical waveguides using a digital ultraviolet (UV) lithography. Grayscale optical exposure with a nonlinear compensation in quadr…
A Cost-Effective Edge Coupler With High Polarization Selectivity for Thin Fil…
Thin film lithium niobate on insulator (LNOI), as an emerging photonic material, provides a promising platform to realize compact, high-speed, and high-efficient electro-optic (EO) modulators. Howe…
Fine-Grained Human-Centric Tracklet Segmentation with Single Frame Supervision
In this paper, we target at the Fine-grAined human-Centric Tracklet Segmentation (FACTS) problem, where 12 human parts, e.g., face, pants, left-leg, are segmented. To reduce the heavy and tedious l…
Deep Learning Enhanced Long-Range Fast BOTDA for Vibration Measurement
In this paper, we propose and experimentally demonstrate a scheme of deep learning enhanced long-range fast Brillouin optical time-domain analysis (BOTDA). The volumetric data from fast BOTDA is de…
Genetic Programming With Niching for Uncertain Capacitated Arc Routing Problem
The uncertain capacitated arc routing problem is an important optimization problem with many real-world applications. Genetic programming is considered a promising hyper-heuristic technique to auto…
A Kriging-Assisted Two-Archive Evolutionary Algorithm for Expensive Many-Obje…
Only a small number of function evaluations can be afforded in many real-world multiobjective optimization problems (MOPs) where the function evaluations are economically/computationally expensive.…
Ultra-Low Phase Noise Measurement of Microwave Sources Using Carrier Suppress…
We propose and demonstrate a photonic delay line based carrier suppression interferometer system for measuring the phase noise of microwave sources. We show both theoretically and experimentally fo…
A Gas-Liquid Sensor Functionalized With Graphene-Oxide on Chalcogenide Tapere…
This work presents a gas-liquid sensor based on chalcogenide etched-tapered fiber (ETF) functionalized with graphene oxide film. Unlike the preparation of conventional tapered fiber sensors, the co…
Large-Scale 3D Baseline Measurement Based on Phase-Stabilized GNSS-Over-Fiber…
Multi-antenna GNSS-over-fiber system is considered an effective solution for three-dimension (3D) baseline measurement. By precisely determining the transmission time delays between the antennas an…
Compact and Low-Insertion-Loss 1 X N Power Splitter in Silicon Photonics
In this paper, a novel design of a 1×N multimode-interference power splitter is proposed and investigated. By using the finite difference time domain method and particle swarm optimization algorit…
