High resolution x-ray investigation of periodically poled lithium tantalate crystals with short periodicity
Marco Bazzan, Cinzia Sada, Nicola Argiolas +5
Domain engineering technology in lithium tantalate is a well studied approach for nonlinear optical applications. However, for several cases of interest, the realization of short p…
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…
