Ghost stochastic resonance in vertical-cavity surface-emitting lasers: experiment and theory.
نویسندگان
چکیده
We study the polarization response of a vertical-cavity surface-emitting laser, driven simultaneously by noise and two (or more) weak periodic signals. In the bistable regime, we observe experimentally the occurrence of stochastic resonance at a frequency that is absent in the input driving signal. The presence of this so-called ghost resonance is confirmed theoretically.

Abstract: In this study, the effects of variation of thickness and the number of quantumwells as well as the contact length were investigated. In this paper, a vertical cavity surfaceemitting laser was simulated using of software based on finite element method. Thenumber of quantum wells was changed from 3 to 9 and the results which are related tooutput power, resonance ...

Injection-Locked Vertical Cavity Lasers exhibit drastically enhanced performance. The 3-dB bandwidth can be increased up to 40 GHz, due to a resonance frequency enhancement. Such VCSELs may play a role in future optical interconnects. c © 2007 Optical Society of America OCIS codes: (140.3520) Injection-locked lasers; (250.7260) Vertical cavity surface emitting lasers

The wavelength splitting between the LP01 and LP11 modes of selectively oxidized, ion implanted, and hybrid ion implanted/selectively oxidized vertical-cavity surface-emitting lasers is studied by experiment and theory. Measured splittings at threshold show marked differences between the different laser structures due to the effects of index guiding and thermal lensing. Theoretical results were...
متن کاملPolarisation Switches in Vertical Cavity Surface Emitting Lasers
The polarization dynamics of a vertical cavity surface emitting laser is investigated as a nonlinear stochastic dynamical system. The polarization switches in the device are considered as activation processes in a two dimensional system with a saddle cycle; the optimal way of switching is determined as the solution of a boundary value problem. The theoretical results are in good agreement with ...
