Localized structures formed through domain wall locking in cavity-enhanced second-harmonic generation
C. Mas Arabí, P. Parra-Rivas, T. Hansson +3
We analyze the formation of localized structures in cavity-enhanced second-harmonic generation. We focus on the phase-matched limit, and consider that fundamental and generated wav…
Nonlinear beam self-imaging and self-focusing dynamics in a GRIN multimode optical fiber: theory and experiments
Tobias Hansson, Alessandro Tonello, Tigran Mansuryan +7
Beam self-imaging in nonlinear graded-index multimode optical fibers is of interest for many applications, such as implementing a fast saturable absorber mechanism in fiber lasers…
Optical frequency combs in quadratically nonlinear resonators
I. Ricciardi, S. Mosca, M. Parisi +7
Optical frequency combs are one of the most remarkable inventions of the last decades. Originally conceived as the spectral counterpart of the train of short pulses emitted by mode…
On-chip self-referencing using integrated lithium niobate waveguides
Yoshitomo Okawachi, Mengjie Yu, Boris Desiatov +4
The measurement and stabilization of the carrier-envelope offset frequency via self-referencing is paramount for optical frequency comb generation which has revo…
