Erratum: Frequency comb dynamics of a 1.3µm hybrid-silicon quantum dot semiconductor laser with optical injection (Optics Letters (2019) 44 (5755) DOI: 10.1364/OL.44.005755)

The effective LEF α_e is obtained by computing over the entire comb spectrum the mean square of α(ν)such as α_e = ^s _1ν ^{1 Z} _comb dν⁰α²(ν⁰), (1) with 1ν the width of the comb spectrum, while ν⁰ is the frequency of the radiation emitted by the laser. Therefore, assuming a QD as a two-level atomic system and that the center of the emitted comb spectrum matches the center frequency of the QD transition, integration of Eq. (1) leads to 1ν = 2√30α_e (2) with 0 the homogeneous broadening of the QD transition. The factor two was missing in [1].
