Topological insight into the non-arrhenius mode hopping of semiconductor ring lasers.

چکیده
We investigate both theoretically and experimentally the stochastic switching between two counterpropagating lasing modes of a semiconductor ring laser. Experimentally, the residence time distribution cannot be described by a simple one-parameter Arrhenius exponential law and reveals the presence of two different mode-hop scenarios with distinct time scales. In order to elucidate the origin of these two time scales, we propose a topological approach based on a two-dimensional dynamical system.

Study of Semiconductor Microring Lasers for use in Wavelength Division Multiplexing (WDM) Telecommunication Networks
In this thesis, the optical characteristics of all-active microring resonators as lasers are studied. The structure of a semiconductor microring laser coupled to a bus waveguide is investigated. The scope of the study is to examine the microring’s laser operation and also emphasize the influence of the key design parameters on single mode and/or unidirectional operation, both being of major con...
متن کاملDesign of External Cavity Semiconductor Lasers to Suppress Wavelength Shift and Mode Hopping
In this report, a model of external cavity semiconductor laser is built, and then based on this model a program is coded for simulating the thermally induced wavelength shift and mode hopping. By comparing the simulation and the published experimental results of two modified ECL designs we found that our simulation results agree very well with the experimental results. Through theoretical analy...
متن کاملMultilongitudinal-mode dynamics in a semiconductor laser subject to optical injection
Multilongitudinal-mode dynamics in a semiconductor laser subject to optical injection are investigated both experimentally and numerically. We found that there are parameter regimes for which the slave laser hops into an adjacent longitudinal mode as we vary the detuning of the optical frequencies between the master and slave laser. A traveling wave model is used to numerically investigate the ...
متن کاملMode Competition in a Fabry P erot Semiconductor laser: Travelling Wave Model with asymmetric dynamical gain
We report and discuss our main results for the multimode dynamics of a Fabry-P erot laser in diierent situations above threshold: mode beating and mode-hopping. A Travelling Wave approximation has been used together with a model with an asymmetric dynamical gain for the semiconductor laser which captures important features needed for the understanding of multimode dynamics.
متن کاملStrong non-Arrhenius temperature dependence of the resistivity in the regime of traditional band transport
When a strong, though non-Arrhenius temperature dependence of electrical resistivity is observed, one usually concludes that the underlying mechanism is variable-range hopping. Unexpectedly, such observations are also made for many semiconductor systems at elevated temperatures, where a variable-range hopping mechanism seems unlikely. A satisfactory explanation for this observation is still lac...
