Two-parameter study of square-wave switching dynamics in orthogonally delay-coupled semiconductor lasers.
We perform a detailed numerical analysis of square-wave (SW) polarization switching in two semiconductor lasers with time-delayed, orthogonal mutual coupling. An in-depth mapping of the dynamics in the two-parameter plane coupling strength versus frequency detuning shows that stable SWs occur in narrow parameter regions that are localized close to the boundary of stability of the pure-mode solu...
متن کاملMutually delay-coupled semiconductor lasers: Mode bifurcation scenarios
We study the spectral and dynamical behavior of two identical, mutually delay-coupled semiconductor lasers. We concentrate on the short coupling-time regime where the number of basic states of the system, the compound laser modes (CLMs), is small so that their individual behavior can be studied both experimentally and theoretically. As such it constitutes a prototype example of delay-coupled la...
متن کاملExperimentally Observed Dynamical Characteristics of Mutually Coupled Semiconductor Lasers With or Without Optoelectronic Feedback
Mutually-coupled semiconductor lasers are of great current interest because of the important insight they provide into coupled physical, chemical, and biological systems. Two semiconductor lasers either with or without optoelectronic feedback are mutually coupled together through optoelectronic paths. It is found that mutual coupling can signi cantly a ect the dynamics of the semiconductor lase...
متن کاملCompound laser modes of mutually delay-coupled semiconductor lasers: bifurcation analysis of the locking region
A system of two mutually delay-coupled semiconductor lasers with a small delay of 170 ps in the coupling is studied. Apart from a possible difference in their optical frequencies, we consider two identical lasers. We show the existence and stability of compound laser modes. They are the basic solutions of the system describing a frequency locked state of the coupled laser system. A characterist...
متن کاملSquare-wave self-modulation in diode lasers with polarization-rotated optical feedback.
The square-wave response of edge-emitting diode lasers subject to a delayed polarization-rotated optical feedback is studied in detail. Specifically, the polarization state of the feedback is rotated such that the natural laser mode is coupled into the orthogonal, unsupported mode. Square-wave self-modulated polarization intensities oscillating in antiphase are observed experimentally. We find ...
