A novel all fibre Q-switched Thulium-doped fibre laser (TDFL) is reported which includes a short length of a Thulium–Holmiumco-doped fibre (THDF) as a saturable absorber. A high repetition rate (27.26 kHz) coupled with a low pulse width ( 19 . 06

A few mode wavelength division multiplexing coupler (WDMC) based on a five-core fiber is proposed to couple pump light with the wavelength of 980 nm into few-mode fiber amplifiers supporting four LP modes at 1550 nm. The WDMC is composed of a few-mod

In this paper, multiple tunable Fano resonances are firstly achieved in an end-coupled system composed of a rectangular cavity and an inverted U-shaped groove. Through increasing a coupling path, dual Fano resonances are tuned to four Fano peaks. Hig

In this paper we consider a cavity optomechanics consists of a two-level atom that interacts with a single-mode quantized field in the presence of a strong driving laser. By evaluating the effective Hamiltonian of the whole system which contains the

We experimentally demonstrate the performance of 16-ary orbital angular momentum shift keying (OAM-SK) decoders based on convolutional neural networks (CNNs) in an underwater optical wireless communication (UOWC) system. We verify the decoding accura

Traditional Fourier ptychographic microscopy (FPM) requires the acquisition of multiple images, which limits the acquisition speed and increases storage requirements. Here, we present a compressed sampling method for FPM (CSFPM), wherein we randomly
