Graphene Actively Mode‐Locked Lasers [PDF]

open access: yesAdvanced Functional Materials, 2018
AbstractActively mode‐locked lasers offer varying degrees of flexibility for a wider range of applications than their passively modulated counterparts, due to their capability for electrically controlled ultrahigh repetition rate operation. Graphene based electrooptic modulators with unique advantages of broad operation bandwidth and ultrafast speed ...

Mode locking in solitary lasers

Optics Letters, 1991
We present an analysis of passively mode-locked lasers in which pulse formation is dominated by the interplay between self-phase modulation and negative dispersion in separate cavity elements. Steady-state pulse parameters and stability issues are discussed.

Noise of mode-locked lasers

IEEE Journal of Quantum Electronics, 1993
A theory of noise in mode-locked lasers is developed that applies to additive pulse mode-locked and Kerr lens mode-locked systems. Equations of motion are derived for pulse energy, carrier linewidth, frequency pulling, and timing jitter. The effect of gain fluctuations, mirror vibrations, and index fluctuations are determined.

Optically injected mode-locked laser

Physical Review E, 2011
We study analytically and numerically a delay differential model of a passively mode-locked semiconductor laser subjected to a single frequency coherent injection. The width of the locking cone is calculated asymptotically in the limit of small injection and compared to that obtained by direct numerical integration of the model equations.

A Mode-Locked Nd:YAG Laser

Journal of Applied Physics, 1968
A mode-locked Nd:YAG laser is described which produces pulses 30 psec in duration at a 2.6 nsec repetition rate. The locking range extends over ≈35 GHz, although the free-running oscillating linewidth is only about 10 GHz. Also discussed is the behavior of the phase of the pulsetrain with changing cavity length.

Colliding pulse mode locked laser

Optical Fiber Communication Conference. Technical Digest Postconference Edition. Trends in Optics and Photonics Vol.37 (IEEE Cat. No. 00CH37079), 2000
The fabrication and performance of a colliding pulse-mode locked laser with an intracavity saturable absorber is described. The laser has a threshold current of 65 mA and differential efficiency of 0.04 mW/mA when coupled into a single-mode fiber. Mode-locked pulses with /spl sim/1 ps pulse width at /spl sim/10 GHz has been obtained.

Mode‐Locked Soliton Lasers

SIAM Review, 2006
A comprehensive treatment is given for the formation of mode-locked soliton pulses in optical fiber and solid state lasers. The pulse dynamics is dominated by the interaction of the cubic Kerr nonlinearity and chromatic dispersion with an intensity-dependent perturbation provided by the mode-locking element in the laser cavity.

Passive Mode-Locking Techniques of Lasers

International Journal of High Speed Electronics and Systems, 1997
In the frequency domain, mode-locking of a laser is to "lock" the relative phase of various iongitudinal modes in order to form pulses. In many applications, passive mode-locking is superior to active mode-locking because the former does not need any external active sources as required for the latter.

Application of a Mode-Locked Laser to Holography

Applied Optics, 1972
A system that uses a mode-locked laser to record double exposure holograms of a rapidly changing object is described. A saturable absorber is used to mode-lock a ruby laser, producing a train of pulses of very short duration. Two of the pulses are selected by rapidly switching a Kerr cell shutter arrangement. When these two pulses are used to produce a
