Multiscale Information Storage of Linear Long-Range Correlated Stochastic Processes
Luca Faes, Margarida Almeida Pereira, Maria Eduarda Silva +4
Information storage, reflecting the capability of a dynamical system to keep predictable information during its evolution over time, is a key element of intrinsic distributed compu…
Surface domain engineering in congruent lithium niobate single crystals: A route to submicron periodic poling
Alessandro C. Busacca, Collin L. Sones, Vasilis Apostolopoulos +2
We describe a technique for surface domain engineering in congruent lithium niobate single crystals. The method is based on conventional electric-field poling, but involves an inte…
Random quasi-phase-matched second-harmonic generation in periodically poled lithium tantalate
Salvatore Stivala, Alessandro C. Busacca, Alessia Pasquazi +3
We observe second harmonic generation via random quasi-phase-matching in a 2.0 μm periodically poled, 1-cm-long, z-cut lithium tantalate. Away from resonance, the harmonic output p…
Nonlinear Disorder Mapping Through Three-Wave Mixing
Alessia Pasquazi, Alessandro Busacca, Salvatore Stivala +2
We implement a simple and powerful approach to characterize the domain distribution in the bulk of quadratic ferroelectric crystals via far-field second-harmonic spectroscopy. The…
Counter-propagating frequency mixing with Terahertz waves in diamond
Matteo Clerici, Lucia Caspani, Eleonora Rubino +6
Frequency conversion by means of Kerr-nonlinearity is one of the most common and exploited nonlinear optical processes in the UV, visible, IR and Mid-IR spectral regions. Here we s…
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…
