Chaotic Internal Dynamics of Dissipative Optical Soliton Molecules

Laser &Photonics Reviews, Volume 17, Issue 8, August, 2023., 2023
Can the analogy between optical soliton molecules and matter molecules be further developed? Do optical soliton molecules allow low‐dimensional chaos? An ultrafast fiber laser experiment with advanced characterization demonstrates bifurcations leading to chaotic relative motions of the bound optical solitons.

Unveiling Laser Radiation of Multiple Optical Solitons by Nonlinear Fourier Transform

Laser &Photonics Reviews, Volume 17, Issue 7, July 2023., 2023
Nonequilibrium multiple soliton dynamics and all‐optical control of multiple solitons drifting are revealed by coherent homodyne detection and nonlinear Fourier transform (NFT) technique, further extending the application of the NFT to the analysis of laser radiation.

Wideband and flat gain series erbium doped fiber amplifier using hybrid active fiber with backward pumping distribution technique

Results in Physics, 2019
A modern wideband and flat gain erbium-doped fiber amplifier (EDFA) is suggested and accomplished, by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-erbium doped fiber (Zr-EDF) as a hybrid active fiber.

Femtosecond Frequency Combs with Few‐kHz Passive Stability over an Ultrabroadband Spectral Range

Laser &Photonics Reviews, Volume 17, Issue 7, July 2023., 2023
The noise properties of fiber‐based frequency combs are studied in a wide parameter range. In specific regions, the free‐running linewidth of the carrier‐envelope offset frequency drops below 1 kHz. All relevant contributions to the phase noise and their interplay are identified.

One-Step Fabrication of 0D Cs₄PbBr₆ Perovskite with Nonlinear Optical Properties for Ultrafast Pulse Generation. [PDF]

Adv Sci (Weinh)
This study focuses on exploring the nonlinear optical properties of 0D Cs4PbBr6 and Cs4PbBr6/CsPbBr3 composites perovskites. For the first time, they are successfully integrated as saturable absorbers into erbium‐doped fiber lasers, achieving conventional soliton mode‐locking operations within the C‐band.

Low‐Temperature Synthesis of Silicon Oxynitride‐Doped Si for Tunable Bragg Gratings Homogeneously Deposited on Si, SiO2, and Borosilicate Substrates and the tip of SM and PM Optical Fibers

Advanced Optical Materials, Volume 11, Issue 12, June 19, 2023., 2023
Synthesis of silicon oxynitride‐doped silicon is demonstrated for the first time with a control in the refractive indices. This technique with a single deposition step also yields high reflective Bragg gratings (BGs) on bulk substrates as well as on the tip of optical fibers.

Broadband Nonlinear Photonics in Zeolite‐Based Selenium Chains

Advanced Photonics Research, Volume 4, Issue 6, June 2023., 2023
Se nanochains are successfully prepared by trapping Se species in the circular 1D channel of AlPO4‐5 (AFI) crystal. Subsequently, the Se@AFI composite materials are used as a broadband saturable absorber to generate the stable mode‐locking pulse in the fiber laser at 1564 and 1043 nm.

Lab‐on‐Fiber Based on Optimized Gallium Selenide for Femtosecond Mode‐Locked Lasers and Fiber‐Compatible Photodetectors

Advanced Photonics Research, Volume 4, Issue 4, April 2023., 2023
Lab‐on‐fiber (LOF) based on optimized ε‐GaSe is proposed to be used for robust femtosecond pulse generation and fiber‐compatible photodetector. Benefiting from the fiber‐compatible ε‐GaSe combined with micro–nano processing, stable femtosecond soliton pulse (≈303 fs, 16.67 MHz, 51.64 dB) output and multiwavelength (520, 808, and 1550 nm) detection are ...
