Polarization of lasing emission in microdisk laser diodes
TE polarization of optical emission from microdisk laser diodes of radius R55 mm, thickness L50.3 mm, is found to dominate both below and above room-temperature lasing threshold current, I th 52 mA. TE emission in the lasing mode at l51560 nm wavelength is due to higher optical gain for TE modes in the quantum well device. In our device geometry, the intrinsic whispering gallery resonances have...
متن کاملLarge spontaneous emission enhancement in InAs quantum dots coupled to microdisk whispering gallery modes
Measuring the enhancement of spontaneous emission decay rates of quantum dot emission coupled to microcavity modes is typically hampered by variable coupling of the quantum dot emission. This is particularly evident in the microdisk cavity since the whispering gallery modes are localized near the disk edge, while quantum dot emitters are typically uniformily distributed throughout the disk. The...
متن کاملEstimation of the spontaneous emission factor for microdisk lasers via the approximation of whispering gallery modes
Microdisk structures have been used to achieve low-threshold lasing. For these microcavity lasers, the spontaneous emission coupling factor p is an important parameter since it determines the threshold current of the laser. Theoretical calculation of p based on the exact solution of the modes in a microdisk is complicated. A simple, approximate method for solving the waveguide modes and the den...

15 صفحه اولLarge spontaneous emission enhancement in plasmonic nanocavities
Cavity–emitter coupling can enable a host of potential applications in quantum optics, from low-threshold lasers to brighter single-photon sources for quantum cryptography1. Although some of the first demonstrations of spontaneous emission modification occurred in metallic structures2,3, it was only after the recent demonstration of cavity quantum electrodynamics effects in dielectric optical c...
