Abstract

We spectrally investigated the regimes of operation of multi-mode semiconductor ring lasers. We report here on an InAs/InGaAsP/InP quantum dot ring laser. The field emitted by both sides of the device is detected with either a power meter or a 6GHz resolution multi-wavelength meter. We present here the mode-resolved PI-curves for different values of the bias current, the dominant wavelength and the side-modesuppression ratio. Opposite to single mode devices, whose dynamics is determined by the coupling of two counter-rotating waves which compete for a common gain, we observed a nontrivial partitioning of power between the two directions and the different longitudinal modes.
