Hybrid integrated mode-locked laser diodes with a silicon nitride extended cavity
Ewoud Vissers, Stijn Poelman, Camiel Op de Beeck +2
Integrated semiconductor mode-locked lasers have shown promise in many applications and are readily fabricated using generic InP photonic integration platforms. However, the passiv…
Efficient Type II Second Harmonic Generation in an Indium Gallium Phosphide on insulator wire waveguide aligned with a crystallographic axis
Nicolas Poulvellarie, Carlos Mas Arabi, Charles Ciret +7
We theoretically and experimentally investigate type II second harmonic generation in III-V-on-insulator wire waveguides. We show that the propagation direction plays a crucial rol…
Analysis of the phase-locking dynamics of a III-V-on-silicon frequency comb laser
Alexis Verschelde, Kasper Van Gasse, Bart Kuyken +3
We present the detailed characterization of the phase dynamics of a telecom hybrid III-V-on-silicon passively mode-locked laser with a ring cavity. We explore the various regimes o…
Supercontinuum generation assisted by dispersive waves trapping in dispersion-managed integrated silicon waveguides
Junxiong Wei, Charles Ciret, Maximilien Billet +3
Compact chip-scale comb sources are of significant interest for many practical applications. Here, we experimentally study the generation of supercontinuum (SC) in an axially varyi…
An on-chip III-V-semiconductor-on-silicon laser frequency comb for gas-phase molecular spectroscopy in real-time
Kasper Van Gasse, Zaijun Chen, Edoardo Vicentini +7
Frequency combs, spectra of evenly-spaced narrow phase-coherent laser lines, have revolutionized precision measurements. On-chip frequency comb generators hold much promise for ful…
Full Vectorial Modeling of Second Harmonic Generation in III-V-on-insulator Nanowires
Charles Ciret, Koen Alexander, Nicolas Poulvellarie +5
We model second harmonic generation in subwavelength III-V-on-insulator waveguides. The large index contrast induces strong longitudinal electric field components that play an impo…
