Indium selenide as a saturable absorber for a wavelength-switchable vector-soliton fiber laserChao Zeng’s research team experimentally demonstrate that indium selenide (In2Se3), a III-VI group layered chalcogenide compound. can be used as a saturable absorber (SA) for a wavelength-switchable vector-soliton fiber laser. The modulation depth of the I...Nov 27, 2019 -
Generation of coexisting high-energy pulses in a mode-locked all-fiber laser with a nonlinear multimodal interference techniqueWei Zhao’s research team demonstrate a passively mode-locked all-fiber laser incorporating a piece of graded-index multimode fiber as a mode-locking modulator based on a nonlinear multimodal interference technique, which generates two types of coexisting h...Nov 27, 2019 -
Simultaneous Wavelength and Format Conversions Based on the Polarization-Insensitive FWM in Free-Space Optical Communication NetworkFree-space optical (FSO) network is an effective way to enhance the interoperability and improve the resource utilization of the FSO communication systems. Since the structure is relatively simple and the nodes are not so many, wavelength conversion-based o...Nov 27, 2019 -
Research on frequency modulation character of the current driven DFB semiconductor laserThis paper presents a study on the issue of current-driven distributed feedback (DFB) semiconductor lasers (LD) experiencing nonlinear laser frequency variation in the course of linear frequency modulation. Cunxiao Gao’s research team establish a theoretic...Nov 27, 2019 -
Star Identification Algorithm Based on Oriented Singular Value Feature and Reliability Evaluation MethodDesheng wen’s research team present a full-sky autonomous star identification algorithm aimed at solving the "lost-in-space" problem in this paper. It mainly consists of two steps: an initial match step and a reliability evaluation step. Oriented singular ...Nov 27, 2019
