All-optical diode in a periodically poled lithium niobate waveguide
TL;DR: In this article, a guided-wave all-optical diode based on engineered quasiphase matching in a LiNbO3 channel waveguide was demonstrated, leading to optical isolation with contrasts as high as 90% at 3.1 W, in agreement with theoretical predictions.

Biocompatibility of ferroelectric lithium niobate and the influence of polarization charge on osteoblast proliferation and function.
N. Craig Carville,Liam Collins,Michele Manzo,Katia Gallo,Bart I. Lukasz,Katey K. McKayed,Jeremy C. Simpson,Brian J. Rodriguez +7 more
TL;DR: The cells showed enhanced proliferation rates and improved osteoblast function through mineral formation on the positively and negatively charged LN surfaces compared to electrostatically neutral x-cut LN and a glass cover slip control, highlighting the potential of LN as a template for investigating the role of charge on cellular processes.

Photoreduction of SERS-active metallic nanostructures on chemically patterned ferroelectric crystals.
N. Craig Carville,Michele Manzo,Signe Damm,Marion Castiella,Liam Collins,Denise Denning,Stefan A. L. Weber,Katia Gallo,James H. Rice,Brian J. Rodriguez +9 more
TL;DR: Metal deposition onto substrates which have been chemically patterned via proton exchange (i.e., without polarization reversal) is demonstrated, demonstrating the suitability of chemically patterning ferroelectrics as SERS-active templates.
Plasmon enhanced Raman from Ag nanopatterns made using periodically poled lithium niobate and periodically proton exchanged template methods
TL;DR: In this paper, the plasmon active properties of Ag nanopattern arrays formed using ferroelectric lithography based on two separate approaches, i.e., periodically poled lithium niobate (PPLN) and periodically proton exchanged (PPE) template methods, were investigated.
Field Induced Evolution of Regular and Random 2D Domain Structures and Shape of Isolated Domains in LiNbO3 and LiTaO3
A. I. Lobov,V. Ya. Shur,Ivan Baturin,E. I. Shishkin,D. K. Kuznetsov,A. G. Shur,M. A. Dolbilov,Katia Gallo +7 more
TL;DR: In this paper, the shape of isolated domains produced by application of the uniform external electric field in different experimental conditions were investigated experimentally in single crystalline lithium niobate LiNbO3 and lithium tantalate LiTaO3.
