Erratum: Physics and applications of quantum dot lasers for silicon photonics (Nanophotonics DOI: 10.1515/nanoph-2019-0570)

After the publication of this article, the authors found out a simple error and hereby correct them as delineated below. (1) The former tells us that depending on the value of the coefficient X, the optical feedback induced frequency shift can exhibit two different behaviors: in the low feedback regime (X < 1), Eq. (19) has only one solution whereas for X < 1, Eq. (19) has more than one solution due to the increase of external cavity modes (ECM), in a number increasing with X hence increasing the modal competition and laser instabilities. This description is incorrect and thereby should be replaced by a correct description as follows The former tells us that depending on the value of the coefficient X, the optical feedback induced frequency shift can exhibit two different behaviors: in the low feedback regime (X < 1), Eq.
