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…
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…
Lasing on hybridized soliton frequency combs
Theodore P. Letsou, Dmitry Kazakov, Pawan Ratra +10
Coupling is an essential mechanism that drives complexity in natural systems, transforming single, non-interacting elements into intricate networks with rich physical properties. H…
Impact of coherent mode coupling on noise performance in elliptical aperture VCSELs for datacom
Cristina Rimoldi, Lorenzo L. Columbo, Alberto Tibaldi +4
We study the dynamical behavior of medium-size multimode VCSELs with an elliptical oxide aperture, selected for the best trade-off between high output power and modulation speed fo…
