Bistable localized emission states in vertical-cavity surface-emitting lasers with frequency-selective feedback — •T. Ackemann1, M. Sondermann1, F. Marino2, and R. Jäger3 — 1Institut für Angewandte Physik, Westfälische Wilhelms-Universität Münster, Corrensstr. 2-4, 48149 Münster, Germany — 2Instituto Mediterráneo de Estudios Avanzados (IMEDEA), Universitat de les Illes Balears, E-07071 Palma de Mallorca, Spain — 3ULM Photonics, Lise-Meitner-Str. 13, 89081 Ulm, Germany
The turn-on characteristics of broad-area bottom-emitting vertical-cavity surface-emitting lasers with frequency-selective feedback by a diffraction grating are studied experimentally. In the vicinity of the threshold, we observe the formation of bistable localized emission states. These states might have applications in potentially massively parallel all-optical switching schemes.
