Graphene-Based Saturable Absorber for Single-Longitudinal-Mode Operation of Highly Doped Erbium-Doped Fiber Laser

IEEE Photonics Journal, 2012
In this paper, a conventional wavelength band (C-band) fiber laser with a tunable single-longitudinal-mode (SLM) output using multilayer graphene as a saturable absorber is demonstrated. The proposed fiber laser uses a short length of highly doped erbium-

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Triple-wavelength fiber ring laser based on a hybrid gain medium actively mode-locked at 10 GHz [PDF]

, 2008
A fiber ring laser based on a hybrid gain medium that produces three simultaneously mode-locked wavelength channels is presented. The lithium niobate based modulator used to actively mode-lock the laser cavity at 10 GHz is birefringence compensated to ...

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Coupled experiment/simulation approach for the design of radiation-hardened rare-earth doped optical fibers and amplifiers [PDF]

, 2011
We developed an approach to design radiation-hardened rare earth -doped fibers and amplifiers. This methodology combines testing experiments on these devices with particle swarm optimization (PSO) calculations.

Multiwavelength Fiber Laser Using Erbium-Doped Twin-Core Fiber and Nonlinear Optical Loop Mirror

IEEE Access, 2019
A multiwavelength fiber laser based on erbium-doped twin-core fiber (ED-TCF) and nonlinear optical loop mirror (NOLM) is proposed and demonstrated in this paper. The ED-TCF is employed as comb filter and gain medium simultaneously.

Cavity Wavelength on Erbium-Doped Fiber Ring Laser Depending on Fabry–Pérot Etalon Steering Angle

Applied Sciences
This study presents the liquid crystal Fabry–Pérot etalon (LC-FP) as the preferred laser wavelength tuning solution within a erbium-doped fiber ring laser architecture. The laser cavity wavelength can be adjusted by applying varying voltages to the LC-FP.

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
