Three-Dimensionally Confined Modes in Micropost Microcavities: Quality Factors and Purcell Factors
We present detailed calculations of the mode structure of distributed-Bragg-reflector micropost microcavities. Two methods are used: a first-principles, finite-difference time-domain model, and an approximate, heuristic model based on the separation of variables. We calculate modal quality factors, as well as enhancement of spontaneous emission rates, from single quantum dots in the microcaviti...
متن کاملproficiency level and factors fostering reticence in efl learners
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
15 صفحه اولOptimization of three-dimensional micropost microcavities for cavity quantum electrodynamics
This article presents a detailed analysis, based on the first-principles finite-difference time-domain method, of the resonant frequency, quality factor (Q), mode volume (V ), and radiation pattern of the fundamental (HE11) mode in a three-dimensional distributed-Bragg-reflector (DBR) micropost microcavity. By treating this structure as a one-dimensional cylindrical photonic crystal containing ...
متن کاملThree-dimensionally Confined Diluted Magnetic Semiconductor Clusters
We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters o f 2 5 A diameter are successfully synthesized inside a glass matrix and fully characterized by chemical analysis, x-ray diffraction, extended x-ray absorption fine structure (EXAFS), and photoluminescence spectroscopy. Effect of size quantization on t...
متن کاملPurcell factors and β−factors in photonic crystal waveguides
We introduce a theoretical formalism to calculate the spontaneous emission rate enhancements (Purcell effect) and propagation mode β-factors from a quantum dot in a planar-photoniccrystal waveguide. Impressive Purcell factors and broadband enhanced β−factors are predicted. c © 2007 Optical Society of America OCIS codes: (230.7400) Waveguides, slab; (270.5580) Quantum electrodynamics Confining s...
