Noise-induced dynamics and photon statistics in bimodal quantum-dot micropillar lasers
Emission characteristics of quantum-dot micropillar lasers (QDMLs) are
located at the intersection of nanophotonics and nonlinear dynamics, which
provides an ideal platform for studying the optical interface between classical
and quantum systems. In this work, a noise-induced bimodal QDML with orthogonal
dual-mode outputs is modeled, and nonlinear dynamics, stochastic mode jumping
and quantum statistics with the variation of stochastic noise intensity are
investigated. Noise-induced effects lead to the emergence of two intensity
bifurcation points for the strong and the weak mode, and the maximum output
power of the strong mode becomes larger as the noise intensity increases. The
anti-correlation of the two modes reaches the maximum at the second intensity
bifurcation point. The dual-mode stochastic jumping frequency and effective
bandwidth can exceed 100 GHz and 30 GHz under the noise-induced effect.
Moreover, the noise-induced photon correlations of both modes simultaneously
exhibit super-thermal bunching effects () in the low injection
current region. The -value of the strong mode can reach over 6 in
the high injection current region. Photon bunching () of both
modes is observed over a wide range of noise intensities and injection
currents. In the presence of the noise-induced effect, the photon number
distribution of the strong or the weak mode is a mixture of Bose-Einstein and
Poisson distributions. As the noise intensity increases, the photon number
distribution of the strong mode is dominated by the Bose-Einstein distribution,
and the proportion of the Poisson distribution is increased in the high
injection current region, while that of the weak mode is reduced. Our results
contribute to the development preparation of super-bunching quantum integrated
light sources for improving the spatiotemporal resolution of quantum sensing
measurements.Comment: 17 pages, 9 figure
