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…
Audiovisual scenes are pervasive in our daily life. It is commonplace for humans to discriminatively localize different sounding objects but quite challenging for machines to achieve class-aware so…
In this work, we report on a high-power all-fiber ultrafast laser system at 2.0 μm that delivers femtosecond pulses with a fundamental repetition rate of 3.0 GHz and a maximum output power of 33.1…
As a powerful supplement to the existing wireless communication technology, free-space optical communication helps to achieve ultra-high-speed wireless communication in many important applications …
In this paper, we analyze the worst-case efficiency loss of online platform designs under a networked Cournot competition model. Inspired by some of the largest platforms in operation today, we stu…
A fiber-optic Mach Zehnder interferometer (MZI) refractive index (RI) sensor based on a double peanut-shaped structure in Er-doped fiber with a section of tapered fiber was fabricated using fusion …
In this paper, we propose and theoretically design a highly sensitive refractive index (RI) sensor based on Vernier effect in three coupled micro-ring resonators (CMRR) with identical geometries. W…
A dual-parameter fiber-optic sensor based on magnetic ionic liquids (MILs) functionalized side-hole fibers (SHFs) has been proposed and experimentally demonstrated for simultaneous measurement of t…
One-stage object detectors are trained by optimizing classification-loss and localization-loss simultaneously, with the former suffering much from extreme foreground-background class imbalance issu…
As a popular tool for producing meaningful and interpretable models, large-scale sparse learning works efficiently in many optimization applications when the underlying structures are indeed or clo…
