As the most common member of the underground pipeline, optical cable has already spread throughout the urban region. By combining the distributed acoustic sensing (DAS) system with the existing opt…
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…
Recently, near-field optical tweezers integrated on a chip based on silicon on insulator (SOI) have attracted more attention and are promising for biological and chemical analyses. Here we propose …
Neural architecture search (NAS) is a challenging problem in the design of deep learning due to its nonconvexity. To address this problem, an adaptive scalable NAS method (AS-NAS) is proposed based…
For 6G in 2030 and beyond, key performance metrics long for terabit-per-second, one-tenth of millisecond latency with zero jitter, millimeter-preci-sion sensing and positioning, and seamless connec…
The Raman optical time-domain reflectometry (ROTDR) uses the Raman backscattering signal of an optical pulse to obtain environmental information along the sensing fiber, with the pulse width limiti…
A fully numerical method for designing efficient adiabatic mode evolution structure (AMES) (referred to as NAMES) is introduced, which can be applied to adiabatic taper, coupler, splitter, mode con…
Massive online open courses (MOOCs) are a booming phenomenon in the digital era, having attracted millions of users around the world to date. At the same time, educational delivery via MOOCs comes …
The advances made in predicting visual saliency using deep neural networks come at the expense of collecting large-scale annotated data. However, pixel-wise annotation is labor-intensive and overwh…
