Multistability manipulation by reinforcement learning algorithm inside mode‐locked fiber laser
Nanophotonics, Volume 13, Issue 16, Page 2891-2901, July 2024.Abstract Fiber mode‐locked lasers are nonlinear optical systems that provide ultrashort pulses at high repetition rates. However, adjusting the cavity parameters is often a challenging task due to the intrinsic multistability of a laser system. Depending on the adjustment of the cavity parameters, the optical output may vary significantly, including Q ...

Half-linear cavity multiwavelength Brillouin-erbium fiber laser [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 Multiwavelength half-linear cavity Brillouin erbium fiber laser (BEFL) has been demonstrated. The half-linear cavity BEFL is formed by utilizing only two circulators: one circulator acts as input and output ports and the other circulator is used to form ...

Dielectric‐Metasurface‐Enhanced Kerr Self‐Modulation for Passively Q‐Switching
Laser &Photonics Reviews, Volume 18, Issue 4, April 2024.By exploiting the enhanced Kerr effect from a periodic array of silicon nanodisks, the Mie resonance of the unit cells enhances is redshifted, achieving a novel transmission modulation for pulsed laser generation. And a stable Q‐switched pulse laser output with a duration of 1.4 µs and a repetition rate of 60 kHz is achieved.

Absolute calibration of fiber-coupled single-photon detector
, 2014 We show a setup for characterising the efficiency of a single-photon-detector absolutely and with a precision better of 1%. Since the setup does not rely on calibrated devices and can be implemented with standard-optic components, it can be realised in ...

Passively mode-locked fiber laser by utilizing TTG film on a D-shaped fiber as a saturable absorber [PDF]
, 2017 In this paper, we propose a mode-locked fiber laser by utilizing single layer Trivial Transfer Graphene film (TTGF) as a saturable absorber (SA). The SA was deposited on the top of a side-polished D-shaped fiber.

Dual-wavelength domain wall solitons in a fiber ring laser
, 2010 We report on the experimental observation of a new type of dark soliton in a fiber laser made of all normal group velocity dispersion fibers. It was shown that the soliton is formed due to the cross coupling between two different wavelength laser beams ...
