Bistable localized emission states in vertical-cavity surface-emitting lasers with frequency-selective feedback — •T. Ackemann1, M. Sondermann1, F. Marino2, and R.

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.
