An Ultra-long adiabatic tapered single mode fiber (UATSMF) is proposed for the Rayleigh back-scattering enhancement and nonlinear suppression. Its Rayleigh back-scattering is enhanced by increasing…
A filter-free photonic method to simultaneously realize radio frequency (RF) image-reject mixing, self-interference cancellation (SIC), and fiber transmission for in-band full-duplex (IBFD) radio-o…
Optical microresonators supported whispering gallery modes (WGMs) are one of the most cost-effective platforms for optical frequency comb generated due to their advantages of ultra-high quality ( Q…
Dynamic multiobjective optimization problems (DMOPs) aim to optimize multiple (often conflicting) objectives that are changing over time. Recently, there are a number of promising algorithms propos…
Using a large sample of unlisted industrial firms in China, we find that a decrease in local governments’ land transfer revenues leads to lower tax avoidance by firms within their jurisdiction. O…
Spatially-adaptive normalization (SPADE) is remarkably successful recently in conditional semantic image synthesis in T. Park et al. 2019 which modulates the normalized activation with spatially-va…
Self-interference and chromatic dispersion are two main limiting factors that influence the recovery of the signal of interest (SOI) in in-band full-duplex (IBFD) radio-over-fiber (RoF) links. An u…
Cylindrical vector (CV) mode as the eigenmodeof optical fibers is a strong candidate for high-capacity mode-division multiplexing (MDM) systems. Based on the Kramers–Kronig (K-K) reception, we ex…
The click feature of an image, defined as the user click frequency vector of the image on a predefined word vocabulary, is known to effectively reduce the semantic gap for fine-grained image recogn…
Microbottle resonators (MBR) have attracted research interest for studying nonlinear optical interactions in last two decades, due to the ultra-tight optical confinement in spaces of three dimensio…
