Modulation response of nanolasers: What rate equation approaches miss

摘要

Rate equation approaches are a standard method to describe and examine the dynamics of various semiconductor lasers, including nanolasers with high spontaneous emission rates. Using the more complex Bloch equation model we investigate the impact of the internal timescales on the modulation response and demonstrate the limitation of rate equation approaches for systems where photon decay rate and polarization decay have similar orders of magnitude.
