Errata and comments on the paper “Slow and fast light in pyramid shaped quantum dots under applied electric fields: The effect of the incident light polarization” [Superlatt. Microstruct. 82 (2015) 313–326]

•Light absorption and the group velocity in a pyramid-shaped nanodot are studied.•Speed control is achieved by varying the intensity and incident light polarization.•Static electric field changes the resonant peak position and group index magnitude.

Along the lines indicated by recent papers, I have revised my results for the absorption and dispersion properties of the pyramid shaped quantum dots under the simultaneous action of incident light and external electric field. The results related to: (i) electronic structure calculations in pyramid shaped quantum dots under applied electric fields and (ii) the tuning of the optical absorption and the group velocity by varying the electric field strength and the ellipticity parameter of the probe light pulse remain unaffected. However, great dissimilarities are found between the old and new results for large intensities of the incident light.
