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…
Transverse photon spin beyond interfaces
Liang Peng, Lingfu Duan, Kewen Wang +6
Photons possess spin degree of freedom, corresponding to clockwise and counter clockwise rotating direction of the fields. Photon spin plays an important role in various applicatio…
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…
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…
