A periodically-poled LiNbO 3 (PPLN) crystal features space-dependent second-order
nonlinear coefficients, which is one of the most important materials to effectively control …

We present an analytical model describing the full electromagnetic propagation in a THz
time-domain spectroscopy (THz-TDS) system, from the THz pulses via Optical Rectification …

The quasi-phase-matching (QPM) technique has drawn increasing attention due to its
promising applications in areas such as nonlinear frequency conversion for generating new …

The inversion of ferroelectric domains in lithium niobate by a scanning focused ultra-violet
laser beam (λ= 244nm) is demonstrated. The resulting domain patterns are interrogated …

We consider the design of photonic circuits that make use of Ti: LiNbO 3 diffused channel
waveguides to generate photons with various combinations of modal, spectral, and …

We present the design and characterization of a zinc-indiffused periodically poled lithium-
niobate ridge waveguide for second-harmonic generation of∼ 390nm light from 780 nm. We …

Starting from the results regarding a nonvacuum technique to fabricate CIGS thin films for
solar cells by means of single‐step electrodeposition, we focus on the methodological …

Lithium niobate photonic circuits have the salutary property of permitting the generation,
transmission, and processing of photons to be accommodated on a single chip. Compact …

We experimentally extend the nonlinear Gaussian to flat-top beam sha** from one to two
dimensions through a three-dimensional nonlinear photonic crystal. Employing a near …

In this paper a detailed study on the harvest of the energy contained in rainfall by means of
piezoelectric transducers is presented. Diverse studies agree on the level of suitable …
