Charge screening strategy for domain pattern control in nano-scale ferroelectric systems

Nava Setter, Tomas Sluka

Strain engineering is a widespread strategy used to enhance performance of devices based on semiconductor thin films. In ferroelectrics strain engineering is used to control the domain pattern: When an epitaxial film is biaxially compressed, e.g. due to la ...

Characterization methodology for lead zirconate titanate thin films with interdigitated electrode structures

Paul Muralt, Robin Nigon, Trygve Magnus Raeder

The accurate evaluation of ferroelectric thin films operated with interdigitated electrodes is quite a complex task. In this article, we show how to correct the electric field and the capacitance in order to obtain identical polarization and CV loops for a ...

Compact Lensless Phase Imager

Michaël Unser, Ferréol Arnaud Marie Soulez

Lensless quantitative phase imaging is of high interest for obtaining a large field of view (FOV), typically the size of the camera chip, to observe biological cell material with high contrast. It has the potential to be widely spread due to its inherent s ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Julien Perruisseau-Carrier, Mihai Adrian Ionescu, Clara-Fausta Moldovan, Michele Tamagnone

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Method and apparatus for measuring the local birefingence along an optical waveguide

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

This invention relates to a system and method to determine the distributed birefringence profile along an optical fibre. Birefringence manifests as different refractive indices for two orthogonal states of polarization of the light propagating in the optic ...

Femtosecond laser direct-write waveplates based on stress-induced birefringence

Yves Bellouard, Christos Edouardos Athanasiou

The use of femtosecond lasers to introduce controlled stress states has recently been demonstrated in silica glass. We use this technique, in combination with chemical etching, to generate and control stress-induced birefringence over a well-defined region ...
