Spontaneous-emission-enabled dynamics at the threshold of a directly modulated semiconductor laser
J. Zou, H. Zhou, C. Jiang +3
Chaos in semiconductor lasers or other optical systems has been intensively studied in the past two decades. However, modulation around threshold has received much less attention,…
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…
Quasi-BIC laser enabled by high-contrast grating resonator for gas detection
H. Zhang, T. Wang, J. Tian +9
In this work, we propose and numerically investigate a two-dimensional microlaser based on the concept of bound states in the continuum (BIC). The device consists of a thin gain la…
High-Q plasmonic crystal laser for ultra-sensitive biomolecule detection
Jiacheng Sun, Tao Wang, Zeinab Jafari +5
Plasmonic lasers provide a paradigm-changing approach for the generation of coherent light at the nanoscale. In addition to the usual properties of coherent radiation, the emission…
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…
Photon bursts at lasing onset and modeling issues in micro-VCSELs
T. Wang, G. P. Puccioni, G. L. Lippi
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…
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…
Onset of lasing in small devices: the identification of the first threshold
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…
High-resolution birefringence cartography of a vertical cavity semiconductor laser
T. Wang, G. L. Lippi
We couple a double-channel imaging technique, allowing for the simultaneous acquisition of high-quality and high-resolution intensity and peak emission wavelength profiles [T. Wang…
