Thresholdless coaxial nanolasers

High-bandwidth metallic coaxial nanolasers are of high interest to investigate laser physics such as thresholdless coherence transitions, and have a large variety of promising applications enabled by their ultrasmall size and large spectral …

We report on the temporal dynamics of second-order correlation function of high-β nanolasers excited with Gaussian-shaped pulses. We show that the nature of output radiation from the nanolaser depends on the excitaiton pulse envelope.
