The past two decades have seen widespread efforts being directed toward the development
of nanoscale lasers. A plethora of studies on single such emitters have helped demonstrate …

Recent studies on exceptional points (EPs) in non-Hermitian optical systems have revealed
unique traits, including unidirectional invisibility, chiral mode switching and laser self …

Ideal integrated light emitters for optical interconnects should be compact in size, high in
modulation bandwidth, efficient in energy consumption and tunable in frequency …

Abstract In a Bose–Einstein condensate, bosons condense in the lowest-energy mode
available and exhibit high coherence. Quantum condensation is inherently a multimode …

We investigate superpositions of two-mode squeezed states (TMSSs), which have potential
applications in quantum information processing and quantum sensing. We study some …

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 …

Two coupled nanolasers exhibit a mode switching transition, theoretically described by
mode beating limit cycle oscillations. Their decay rate is vanishingly small in the …

Synchronization of coupled oscillators at the transition between classical physics and
quantum physics has become an emerging research topic at the crossroads of nonlinear …

We propose a theoretical model of a master equation for cathodoluminescence (CL). The
master equation describes simultaneous excitation of multiple emitters by an incoming …

Based on a rate equation model for single-mode two-level lasers, two algorithms for
stochastically simulating the dynamics and steady-state behaviour of micro-and nanolasers …
