A hybrid mode locked laser as millimetre wave modulated data source for radio-over-fiber systems [PDF]

open access: yes, 2009
The paper presents a characterisation of a hybrid mode locked laser under external injection locking. It shows how such a system can be used to transmit baseband data without the requirement of an external ...

Models for Passively Mode-Locked Fiber Lasers [PDF]

open access: yes2008 10th Anniversary International Conference on Transparent Optical Networks, 2008
We give a review of theoretical approaches we have recently developed for the description of passively mode-locked fiber lasers. Mode-locking is assumed to be obtained with nonlinear polarization rotation. The first approach takes the form of a cubic Ginzburg-Landau equation where the coefficients take into account the orientation of the phase plates ...

860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)

open access: yesResults 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

Intensity noise of mode-locked fiber lasers

open access: yesOptics Letters, 2009
Intensity noise of mode-locked fiber lasers is characterized systematically for all major mode-locking regimes over a wide range of parameters. We find that equally low-noise performance can be obtained in all regimes. Losses in the cavity influence noise strongly without a clear trace in the pulse characteristics.

A millimetre wave phase shifter using a 40GHz hybrid mode locked laser [PDF]

open access: yes, 2008
In this paper, electrical injection locking of a modelocked laser is used to create a millimetre wave phase shifter. The phase shift is measured directly using a vector network analyzer enabling straightforward characterization of such systems.

Distributed Kerr-Lens Mode-Locking in a Fiber Laser

open access: yesOSA Advanced Photonics Congress (AP) 2020 (IPR, NP, NOMA, Networks, PVLED, PSC, SPPCom, SOF), 2020
We introduce the concept of distributed Kerr-lens mode-locking in GRIN fiber lasers. Our analysis demonstrates that proper control of spectral and spatial graded dissipation results in the self-emergence of stable dissipative solitons.

TE-like mode analysis of microsystem InGaAsP/InP semiconductor resonator generating 20 GHz repetition rate pulse trains

open access: yesResults in Physics, 2018
In microsystem technologies, the microring resonators (MRRs) can be used as a filter device. A wavelength-selective modified add-drop MRR filter is used for adding and dropping a particular wavelength in order to control the light propagation within the ...
