"Phase Transitions" in small systems: why standard threshold definitions fail for nanolasers
G. L. Lippi, T. Wang, G. P. Puccioni
Since the development of micro- and nanolasers, the question of laser threshold has been subject to debate. Different definitions have been used to try and establish its occurrence…
Second-order correlation function supported optical sensing for particle detection
T. Wang, C. Jiang, J. Zou +6
We propose a new sensing method based on the measurement of the second-order autocorrelation of the output of micro- and nanolasers with intensity feedback. The sensing function is…
Methodological investigation into the noise influence on nanolasers' large signal modulation
T. Wang, J. L. Zou, G. P. Puccioni +5
Nanolasers are considered ideal candidates for communications and data processing at chip-level thanks to their extremely reduced footprint, low thermal load and potentially outsta…
Photon statistics and dynamics of nanolasers subject to intensity feedback
T. Wang, Z. L. Deng, J. C. Sun +4
Using a fully stochastic numerical scheme, we investigate the behaviour of a nanolaser in the low-coherence regime at the transition between spontaneous emission and lasing under t…
Dynamics of a micro-VCSEL operated in the threshold region under low-level optical feedback
Tao Wang, Xianghu Wang, Zhilei Deng +4
Semiconductor lasers are notoriously sensitive to optical feedback, and their dynamics and coherence can be significantly modified through optical reinjection. We concentrate on th…
Photon bursts at lasing onset and modeling issues in micro-VCSELs

Spontaneous photon bursts are observed in the output collected from a mesoscale semiconductor-based laser near the lasing threshold. Their appearence is compared to predictions obt…
Analytical vs. Numerical Langevin Description of Noise in Small Lasers
G. L. Lippi, J. Mørk, G. P. Puccioni
We compare the analytical and numerical predictions of noise in nano- and microcavity lasers obtained from a rate equation model with stochastic Langevin noise. Strong discrepancie…
Exploration of Micro-VCSEL Ultra-low Biasing Scheme for Pulse Generation
Tao Wang, Gaofeng Wang, Gian Piero Puccioni +1
The generation of optical pulses at ultra low bias level, thus low energy cost, is explored in a commercial microcavity semiconductor laser in view of testing the principle of ener…

Tao Wang, Gian Piero Puccioni, Gian Luca Lippi
We present a simple and flexible technique for identifying the onset of coherent emission in lasers, from the mesoscale to the nanoscale, which makes use of photon counting and a s…
Superthermal light emission and nontrivial photon statistics in small lasers
T. Wang, D. Aktas, O. Alibart +4
Photon statistical measurements on a semiconductor microlaser, obtained using single-photon counting techniques, show that a newly discovered spontaneous pulsed emission regime pos…
