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…
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…
Driven bright solitons on a mid-infrared laser chip
Dmitry Kazakov, Theodore P. Letsou, Marco Piccardo +13
Despite the ongoing progress in integrated optical frequency comb technology, compact sources of short bright pulses in the mid-infrared wavelength range from 3 μm to 12 μm so far…
