The spectrum of microdisk lasers
A model for quantitative analysis of microdisk laser emission spectra is presented. Conformal mapping is used to determine radial and azimuthal eigenvalues, eigenvectors, and cavity Q corresponding to leaky optical resonances in an optically transparent dielectric disk. The effects of gain and loss in a microcavity active medium are also included in the model. Our results compare well with expe...
متن کاملResonant modes and laser spectrum of microdisk lasers
New semiconductor microdisk and microcylinder resonant cavities have been studied with measured lasing emission wavelength at l51550 nm, l5980 nm, and l5510 nm. Position in a cylinder is specified by natural axial coordinate z, radial coordinate r, and azimuthal angle u. Isolated short cylinders are disks of thickness L. The design and optimization of a semiconductor microdisk laser is critical...
متن کاملDynamics of GaAsÕAlGaAs microdisk lasers
Dynamic response of a GaAs/AlGaAs microdisk laser has been experimentally investigated using femtosecond optical pumping. Below the lasing threshold, the delay time of the emission pulse from the microdisk hardly changes with the pump power. Above the lasing threshold, the delay time is shortened dramatically, and it decreases with increasing the pump power. The theoretical simulation based on ...
متن کاملWhispering-gallery mode microdisk lasers
A new microlaser design based on the high-reflectivity whispering-gallery modes around the edge of a thin semiconductor microdisk is described and initial experimental results are presented. Optical confinement within the thin disk plane results in a microresonator with potential for single-mode, ultralow threshold lasers. Initial experiments use selective etching techniques in the InP/InGaAsP ...
متن کاملDynamical localization in microdisk lasers.
We demonstrate the lasing action from a dynamically localized mode in a microdisk resonator with rough boundary. Although substantial boundary roughness and surface defects in our devices imply strong light scattering and destroy the regular whispering gallery modes, the destructive interference of the scattered light leads to the dynamical Anderson localization in the phase space of the system...
