Paper Abstract

In this work we extract a novel formula for optical absorption coefficient of Quantum Dots (QDs) in frame of 8band k.p modeling. Also this is useful for any other several band k.p frame. Using this formula, we analyze and simulate absorption spectra for a typical InAs/In0.4Ga0.6As QD, both for TE and TM components of absorption spectra. Size and alloy fraction of QD is chosen such that the absorption spectra has some components around 1.55μm that will be applicable for single photon fiber optic communication.
