Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. RakiÄ, Dragan Indjin +46
Quantum cascade lasers (QCLs) are unipolar semiconductor lasers first demonstrated in 1994. Since then, they have played a central role in advancing mid-infrared and terahertz phot…

Effective Rabi frequency in semiconductor lasers and the origin of self-starting harmonic frequency combs
Carlo Silvestri, Franco Prati, Massimo Brambilla +2
Optical frequency combs have become a key research topic in optics and photonics. A peculiar comb state is the harmonic frequency comb (HFC), where optical lines are spaced by inte…
