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.

860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)
Results in Physics, 2019 We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated

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.

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 ...
