Nanosecond Fiber Laser Step-Tunable From 3.87 to 4.5 μm in HBr-Filled Hollow…

We report here a wavelength widely step-tunable nanosecond 4 μm fiber laser based on HBr-filled hollow-core fibers (HCFs), which is pumped by an acousto-optic modulated narrow linewidth 2 μm thul…

Efficient Relational Sentence Ordering Network

In this paper, we propose a novel deep Efficient Relational Sentence Ordering Network (referred to as ERSON) by leveraging pre-trained language model in both encoder and decoder architectures to st…

Solving Nonsmooth and Nonconvex Compound Stochastic Programs with Application…

This paper studies a structured compound stochastic program (SP) involving multiple expectations coupled by nonconvex and nonsmooth functions. We present a successive convex programming-based sampl…

On Degenerate Doubly Nonnegative Projection Problems

The doubly nonnegative (DNN) cone, being the set of all positive semidefinite matrices whose elements are nonnegative, is a popular approximation of the computationally intractable completely posit…

Asymptotic Properties of Stationary Solutions of Coupled Nonconvex Nonsmooth …

This paper has two main goals: (a) establish several statistical properties—consistency, asymptotic distributions, and convergence rates—of stationary solutions and values of a class of coupled…

Towards High-Power Densely Step-Tunable Mid-Infrared Fiber Source From 4.27 t…

Soft-glass fiber lasers have attracted lots of attentions as they are most likely to achieve compact, stable, and highly efficient mid-infrared emission, which has unique applications in many field…

Investigation of Spontaneous Raman Scattering in Few-Mode Fibers : Dependence…

We study Raman gain in few-mode fibers (FMFs) by measuring spontaneous Raman scattering in polarization-maintaining FMF, mode-maintaining FMF and common FMF. The results show that the intensities o…

A Proposal for a High-Sensitivity Optical MEMS Accelerometer With a Double-Mo…

A proposal for a high-precision accelerometer based on a silicon optical microelectromechanical system (MEMS) is presented in this article. The device operating principle is that a sensitive mechan…
