Mode locking of semiconductor lasers in a coupled-cavity configuration with a strongly coupled empty auxiliary cavity
Mode locking of semiconductor lasers in a coupled-cavity configuration with an empty auxiliary cavity is studied theoretically. The empty auxiliary cavity, when strongly coupled to the main cavity, is found to influence the pulsation situation significantly. The predicted pulse widths and chirp parameters in the steady state are in good agreement with the experimental measurements. The influenc...
متن کاملCrossover from polariton lasing to exciton lasing in a strongly coupled ZnO microcavity.
Unlike conventional photon lasing, in which the threshold is limited by the population inversion of the electron-hole plasma, the exciton lasing generated by exciton-exciton scattering and the polariton lasing generated by dynamical condensates have received considerable attention in recent years because of the sub-Mott density and low-threshold operation. This paper presents a novel approach t...
متن کاملStrongly coupled magnons and cavity microwave photons.
We realize a cavity magnon-microwave photon system in which a magnetic dipole interaction mediates strong coupling between the collective motion of a large number of spins in a ferrimagnet and the microwave field in a three-dimensional cavity. By scaling down the cavity size and increasing the number of spins, an ultrastrong coupling regime is achieved with a cooperativity reaching 12,600. Inte...
متن کاملLasing without inversion: Gain enhancement through spectrally colored population pumping.
We propose the use of spectrally colored rather than white (i.e., incoherent) population pumping in lasing-without-inversion schemes. We show that colored pumping can lead to a significant enhancement in gain by presenting explicit results for the gain in a three-level ladder system. These results are obtained from Monte Carlo simulations of the coupled density-matrix-equations, which, for a co...
متن کاملLasing action in strongly coupled plasmonic nanocavity arrays.
Periodic dielectric structures are typically integrated with a planar waveguide to create photonic band-edge modes for feedback in one-dimensional distributed feedback lasers and two-dimensional photonic-crystal lasers. Although photonic band-edge lasers are widely used in optics and biological applications, drawbacks include low modulation speeds and diffraction-limited mode confinement. In co...
