Design of Silicon Photonic microring resonators with complex waveguide cross-sections and minimal non-linearity
Stefania Cucco, Marco Novarese, Sebastian Romero Garcia +2
We present a model and a rigorous method to calculate the transmission coefficient of silicon micro-rings with complex waveguide cross-section including non-linear effects and self…

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…

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…
