WebFeb 1, 1998 · Coexisting attractors, which arise from different external-cavity modes of the same longitudinal mode of the solitary laser, retain distinct stability properties, particularly when the laser is biased far above threshold and subjected to moderately strong optical feedback from a distant reflector. When the laser is modeled by the Lang and Kobayashi … Webis the threshold gain of solitary laser given by, = + r f b tho L R R k n c G 1 ln 2 1 (2.4) and G p is the gain of mode p whose wavelength is λ p. G p is defined such that the suppression by mode itself and both p the symmetric gain suppression (SGS) and asymmetric gain suppression (AGS) by other modes q ≠ p are taken into account.

WebWe analyze the performance of a Ti:sapphire self-mode-locked laser with near-zero second- and third-order dispersion. Our simulations show that, in the presence of fourth-order dispersion, solitary laser pulses can be supported within a wide parameter range, close to the experimental values of these parameters. We also conclude that it is possible to … WebWe report the experimental results to continuously tune the coherence length of a semiconductor laser using an optical feedback scheme. The coherence length can be controlled by adjusting the feedback strength when a semiconductor laser operates in a coherence collapse regime. Fine structures of the fringe visibility of the laser output show … east rockaway fd

Strain induced polarization chaos in a solitary VCSEL - ResearchGate

WebA simple reservoir computing (RC) system based on a solitary semiconductor laser under an electrical message injection is proposed, and the performances of the RC are numerically investigated. Considering the lack of memory capacity (MC) in such a system, some auxiliary methods are introduced to enhance the MC and optimize the performances for … Webequal to the unmodulated linewidth of the laser. The linewidth of the external-cavity laser will be measured with this method. The gated-sinewave method was first tested on the solitary laser to prove its usefulness and accuracy for measuring laser linewidth. The solitary laser was modulated with a 500-MHz IO 10 Frequency (MHz) (a) 0 0: 5 1 .o WebSolitary plasmacytosis of the larynx is a clinically unusual event. It may cause hoarseness or airway obstruction and usually needs surgical excision. ...
