Lett. 99, 231103 (2011); 10.1063/1.3665955Multiwavelength fabrication of vertical-cavity surface-emitting lasers based on asymmetric one-dimensional photonic crystalWe present the wave propagation characteristics of photonic quantum ring lasers with clear evidence of the evanescence-propagation crossover behavior. The data obtained from the fiber probe measurements of 15-36 m disk size lasers show that the Rayleigh's whispering gallery modes always give rise to the propagation mode, with the crossover ranges of 55-80 m. The three-dimensional but chiral and broken z-axis symmetry nature of the photonic quantum ring cavity appears to guarantee such a crossover to the propagation in general.

Spectral analysis of a three-dimensional photonic quantum ring laser with a square microcavity

“…9 We previously reported a 3D RFP spectral analysis of a PQR laser using a torus knot model 10 and a 3D torus approach with angular quantization analysis. 12 In this paper, we propose a simple theoretical model to explain the 3D emission modes of a PQR laser with a square microcavity and report that there is a good agreement between the theory and experimental observations of multimode spectra. 12 In this paper, we propose a simple theoretical model to explain the 3D emission modes of a PQR laser with a square microcavity and report that there is a good agreement between the theory and experimental observations of multimode spectra.…”

Directional emission from a microdisk resonator caused by a linear defect

“…Lasers for λ ≈ 0.8µm [16][17][18] have n ≈ 3.1 and also rather small M (30 < ∼ M < ∼ 300). With maximal M = 300 we get 89…”

LaGuerre–Gaussian Emission Properties of Photonic Quantum Ring Hole-Type Lasers

“…These holes were defined by chemically assisted ion-beam etching and planarized by polyimide for stripe electrode extending to the center of the top mesa or the border of the hole. Details of the PQR structure and fabrications were well described before [1], [8], [10]. Fig.…”
