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…
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…
Highly Sensitive Bending Sensor Based on Multicore Optical Fiber With Diagona…
A high-sensitivity bending sensor based on multi-core fiber Bragg gratings (MCFBGs) is presented and demonstrated. The bending sensor is based on FBGs fabricated on the symmetric distribution cores…
Using Standard 2×2 MIMO to Increase Capacity of Spatial Multiplexing with OA…
Modal multiplexing can greatly increase fiber capacity, but often at the cost of high digital processing with multiple-input multiple-output (MIMO) algorithms. The use of orbital angular momentum (…
Robust Inventory Management: A Cycle-Based Approach
Problem definition: We study the robust formulation of an inventory model with positive fixed ordering costs, where the unfulfilled demand is either backlogged or lost, the lead time is allowed to …
Dual-FBG and F-P Cavity Compound Optical Fiber Sensor for Simultaneous Measur…
A dual-FBG and F-P cavity compound optical fiber sensor based on a multi-core fiber (MCF) is proposed. A hollow core fiber (HCF) was fused between a single-mode fiber (SMF) and a MCF to form the F-…
Actively Controllable Beam Steering Optical Wireless Communication (OWC) Usin…
We put forward and present a demonstration of an actively controlled optical beam steering optical wireless communication (OWC) system based on an integrated actively steerable optical phased array…
Phase Off-Axis Modulation Metasurface for Orbital Angular Momentum Mode Multi…
Orbital angular momentum (OAM) mode multiplexing provides a promising solution for enlarging communication capacity density. Although various OAM mode multiplexing technologies have been investigat…
Microfiber Bragg Grating Bonded Using Tapered Cantilever for High-Sensitivity…
A microfiber Bragg grating (MFBG) bonded using tapered cantilever was designed to improve ultrasonic sensitivity, and was investigated using experimental, theoretical, and numerical methods. The ul…
Top-Illuminated Avalanche Photodiodes With Cascaded Multiplication Layers for…
In this work, a novel top-illuminated avalanche photodiode (APD) with a In 0.52 Al 0.48 As multiplication (M-) layer is demonstrated. The cascaded M-layer design combined with the unique p-side up …
