A WIDEBAND AND FLAT-GAIN OF AN AMPLIFIER BY USING ZIRCONIA-BASED ERBIUM-DOPED FIBER (ZR-EDF) FOR SINGLE PASS PPERATION

Jurnal Teknologi, 2016
An amplification for single pass operation was demonstrated by using Zirconia-based erbium-doped fiber (Zr-EDF). 1 m is the optimum length due to overall high gain and minimal noise figure from 1520 nm to 1620 nm. The highest gain is 28.62 dB at 1555 nm with the input signal and pump power are fixed at -30 dBm and 130 mW, respectively. At input signal -

Multiwavelength erbium-doped fiber laser based on a nonlinear amplifying loop mirror assisted by un-pumped EDF

Optics Express, 2012
A multiwavelength erbium-doped fiber (EDF) laser based on a nonlinear amplifying loop mirror (NALM) is proposed and experimentally demonstrated. The NALM provides intensity-dependent transmissivity to equalize different-wavelength powers and the transmission can be uniquely optimized by controlling the cavity loss associated with a section of un-pumped

Hyperspectral Coherent Raman Scattering (CRS) Microscopy Based on a Rapidly Tunable and Environmentally Stable Fiber Laser

Laser &Photonics Reviews, Volume 17, Issue 12, December 2023., 2023
Hyperspectral Coherent Raman Scattering microscopy is capable of distinguishing molecules in complex heterogeneous systems by probing multiple Raman resonances. A rapidly tunable two‐color fiber laser is demonstrated. The superior noise performance of this system is evaluated by the side‐by‐side comparison with data from a commercial optical parametric

Emerging 2D Materials with Nonparabolic Bands for Ultrafast Photonics

Small Science, Volume 3, Issue 10, October 2023., 2023
Materials with nonparabolic bands focus on different applications in ultrafast photonics, such as ultrafast carrier dynamics and nonlinear optical response. Linear dispersive Dirac bands have massless electrons like a photon, while nondispersive flat bands host electrons with an infinite mass.

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.

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.

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.

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.
