  In this work, robustness of controlled density of optical states in doubly
driven artificial atoms is studied under phonon dissipation. By using both
perturbative and polaron approaches, we investigate the influence of
carrier-phonon interactions on the emission properties of a two-level
solid-state emitter, simultaneously coupled to two intense distinguishable
lasers. Phonon decoherence effects on the emission spectra are found modest up
to neon boiling temperatures ($\sim 30$ K), as compared with photon generation
at the Fourier transform limit obtained in absence of lattice vibrations (zero
temperature). These results show that optical switching and photonic modulation
by means of double dressing, do not require ultra low temperatures for
implementation, thus boosting its potential technological applications.
