Second harmonic generation in surface periodically-poled lithium niobate waveguides: on the role of multiphoton absorption
M. Cherchi, S. Stivala, A. Pasquazi +5
Second harmonic generation is investigated in lithium niobate channels realized by proton exchange and quasi-phase-matched by surface periodic-poling. The reduction in conversion e…

Exploiting the optical quadratic nonlinearity of zincblende semiconductors for guided-wave terahertz generation: a material comparison
Matteo Cherchi, Alberto Taormina, Alessandro C. Busacca +6
We present a detailed analysis and comparison of dielectric waveguides made of CdTe, GaP, GaAs and InP for modal phase matched optical difference frequency generation (DFG) in the…
