Efficient single-pixel imaging based on a compact fiber laser array and untrained neural network

Frontiers of Optoelectronics
This paper presents an efficient scheme for single-pixel imaging (SPI) utilizing a phase-controlled fiber laser array and an untrained deep neural network. The fiber lasers are arranged in a compact hexagonal structure and coherently combined to generate

Continuous-Variable Measurement-Device-Independent Quantum Key Distribution in the Terahertz Band

Photonics
We have introduced, for the first time, a protocol for Continuous-Variable Measurement-Device-Independent Quantum Key Distribution (CV-MDI-QKD) in the terahertz (THz) frequency band. We have conducted a secret key rate analysis against collective attacks.

Dissipation-Induced Photon Blockade in the Anti-Jaynes–Cummings Model

Photonics
Due to the fundamental differences between the quantum world and the classical world, some phenomena, such as entanglement and wave–particle duality, only exist in the quantum realm.

Study of Optical Rogue Waves in Two-Dimensional Disordered Lattices

Photonics
We probed the impact of both the degree of disorder and nonlinearity on rogue waves (RWs) in two-dimensional disordered lattices. Our results unveiled that an increase in the disorder level under linear conditions heightened the probability of RW ...

A Micro-Mach–Zehnder Interferometer Temperature Sensing Design Based on a Single Mode–Coreless–Multimode–Coreless–Single Mode Fiber Cascaded Structure

Photonics
In this paper, a temperature sensing scheme with a miniature MZI structure based on the principle of inter-mode interference is proposed. The sensing structure mainly comprises single mode–coreless–multimode–coreless–single mode fibers (SCMCSs), which ...

Investigating changes in the electric field profiles of transverse modes in fibres due to bending

IET Optoelectronics
A model is presented for calculating the electric field profiles of transverse modes in fibres. Using this model, the electric field propagation of transverse modes was calculated and compared in both bent and straight Yb and Ho fibres.

High-Efficiency Dynamic Three-Dimensional Topography Measurement Using the Phase Shift Generation Method

Photonics
In the fringe projection profilometry (FPP), the traditional phase-shifting (TPS) algorithm and the Fourier transform (FT) algorithm are beset with a conundrum where measurement efficiency and conflicts with measurement accuracy, thereby limiting their ...
