Thermo-optical spiking and mixed-mode oscillations in injected Kerr microcavities

Autor: Koch, Elias R., Javaloyes, Julien, Gurevich, Svetlana V.

We investigate the nonlinear dynamics of vertically emitting Kerr microcavities under detuned optical injection, considering the impact of slow thermal effects. Our model integrates thermal detuning caused by refractive index shifts due to heating. T

Pulse instabilities in harmonic active mode-locking: a time-delayed approach

Autor: Koch, Elias R., Gurevich, Svetlana V., Javaloyes, Julien

We propose a time-delayed model for the study of active mode-locking that is valid for large values of the round-trip gain and losses. It allows us to access the typical regimes encountered in semiconductor lasers and to perform an extended bifurcati

Square Waves and Bykov T-points in a Delay Algebraic Model for the Kerr-Gires-Tournois Interferometer

Autor: Stöhr, Mina, Koch, Elias R., Javaloyes, Julien, Gurevich, Svetlana V., Wolfrum, Matthias

We study theoretically the mechanisms of square wave formation of a vertically emitting micro-cavity operated in the Gires-Tournois regime that contains a Kerr medium and that is subjected to strong time-delayed optical feedback and detuned optical i

Temporal localized states and square-waves in semiconductor micro-resonators with strong time-delayed feedback

Autor: Koch, Elias R., Seidel, Thomas G., Javaloyes, Julien, Gurevich, Svetlana V.

In this paper we study the dynamics of a vertically-emitting micro-cavity operated in the Gires-Tournois regime that contains a semiconductor quantum-well and that is subjected to strong time-delayed optical feedback and detuned optical injection. Us

Square wave generation in vertical external-cavity Kerr-Gires-Tournois interferometers

Autor: Koch, Elias R., Seidel, Thomas G., Gurevich, Svetlana V., Javaloyes, Julien

We study theoretically the mechanisms of square-wave (SW) formation in vertical external-cavity Kerr-Gires-Tournois interferometers in presence of anti-resonant injection. We provide simple analytical approximations for their plateau intensities and
