Quantum cascade laser roadmap
Carlo Silvestri, Aleksandar D. Rakić, 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…
Terahertz semiconductor laser chaos
Binbin Liu, Carlo Silvestri, Kang Zhou +12
Chaos characterized by its irregularity and high sensitivity to initial conditions finds various applications in secure optical communications, random number generations, light det…
Unified theory for frequency combs in ring and Fabry-Perot quantum cascade lasers: an order-parameter equation approach
