Multi-Wavelength Spatiotemporal Mode-Locked Fiber Laser at 1.55 μm

Photonics, 2022
We propose and demonstrate an effective and simple multi-wavelength spatiotemporal mode-locked (STML) laser. The laser introduces a multimode interference (MMI) effect using the core diameter mismatch of the fibers, thus enabling simultaneous mode ...

Spatiotemporal Mode-Locking as Multidimensional Optimization [PDF]

Conference on Lasers and Electro-Optics, 2019
We outline a theoretical framework to understand the multitude of new mode-locked states possible in multi-transverse mode resonators. Full-3D measurements of mode-locked states comprising roughly 30 million modes agree with theoretical expectations.

3 W average-power high-order mode pulse in dissipative soliton resonance mode-locked fiber laser

Nanophotonics, 2021
Recently high-order modes (HOMs) lasers have been extensively investigated due to their potential applications in mode-division multiplexing. In this paper, we present two schemes of generating HOMs from the mode-locked fiber lasers (MLFLs) in the ...

Tunable spatiotemporal mode-locked fiber laser at 1.55 μm

Optics Express, 2021
We report the spatiotemporal mode-locked multimode fiber laser operating at 1.55 µm based on semiconductor saturable absorber mirrors with the mode-locking threshold as low as 104 mW. Benefiting from the multimode interference filtering effect introduced in the laser cavity not only the central wavelength can be continuously tuned from 1557 nm to 1567 ...

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

, 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.
