The decay dynamics of the classical electromagnetic field in a leaky optical resonator supporting a single mode coupled to a structured continuum of modes (reservoir) is theoretically investigated, and the issue of threshold condition for lasing in presence of an inverted medium is comprehensively addressed. Specific analytical results are given for a single-mode microcavity resonantly coupled ...

The optical coupling between dual elements of photonic crystal vertical cavity surface emitting laser arrays is characterized. optically coupled microcavity lasers have independent bias injection currents. Output power and beam analysis measurements are used to quantify the effects coherence in nominally 850 nm arrays. Modelling experiment show how influenced by lattice period current into elem...

Abstract Optical microcavities have emerged as promising platforms for ultrasound detection. One of the main tendencies in recent studies is to develop high- Q microresonators ultrasensitive detection, while nonlinear optical effects become significant but are generally neglected. Here, we propose a thermal-assisted microcavity Raman laser Acoustic waves modulate resonant frequency cavity mode,...

Significance Microlasers in near-degenerate supermodes play a pivotal role for studies of non-Hermitian physics, novel light sources, and advanced sensors. However, the widely observed beating phenomena single-mode nature stimulated scattering have been generating lasing characteristic dilemma. In this article, we experimentally elucidate spectral paradox by investigating dynamics supermode Ram...

We demonstrate the occurrence of spatial multistability using laterally confined microcavity exciton-polaritons. By coherently exciting with a blue detuned laser a series of confined polariton modes, we investigate the effects of multistability on the transmitted laser beam as a function of the excitation power. At each threshold of the hysteresis loop, a switching of the mode profile of the la...
