Ultrafast optical properties and applications of anisotropic 2D materials. [PDF]

Nanophotonics
Abstract Two‐dimensional (2D) layered materials exhibit strong light‐matter interactions, remarkable excitonic effects, and ultrafast optical response, making them promising for high‐speed on‐chip nanophotonics. Recently, significant attention has been directed towards anisotropic 2D materials (A2DMs) with low in‐plane crystal symmetry. These materials

Experimental Measurement of Absorption Coefficients for Effective Erbium-Doping Concentration to Optimize Few-Mode Erbium-Doped Fiber Amplifiers with Low Differential Mode Gain

Photonics, 2021
According to the analytical expression for modal gain of few-mode erbium-doped fiber amplifiers (FM-EDFAs), we propose a method of measuring the absorption loss coefficients of few-mode signals in few-mode erbium-doped fibers (FM-EDFs) by extrapolating ...

A MHz−Level Swept Source by Time Stretching the Shot−Noise Limited Supercontinuum Based on a Mode−Locked Laser and the Application in Optical Coherence Tomography

Laser &Photonics Reviews, Volume 19, Issue 22, November 19, 2025.
This work pioneers a 5.7 MHz all−fiber mode−locked laser−based broadband swept−source OCT system, achieving record−breaking performance: 11.4 µm axial resolution and 119 mm detection range. The system demonstrates exceptional coherence and stability, overcoming traditional trade−off between imaging speed and detection range.
