Theoretical estimation of optical absorption coefficient inside an InAs/InGaAs semiconductor Quantum Dot
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/In 0.4 Ga 0.6 As QD, both for T...

Summary: | 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/In 0.4 Ga 0.6 As 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. |
