New paper in OLEN showing a polarization insensitive binary phase ferroelectric LC modulator
Our last paper published in Optics and Lasers in Engineering (OLEN) is entitled Ferroelectric liquid-crystal modulator with large switching rotation angle for polarization-independent binary phase modulation.
Here we show a ferroelectric liquid crystal (FLC) modulator with a non-standard large switching rotation angle, close to 90◦. The modulator acts as a switchable wave-plate with an in-plane rotation of the principal axis under the action of a bipolar voltage. The modulator is shown to behave as a binary 𝜋 phase modulator independently of the input state of polarization.
This work is part of the PhD Thesis of Esther Nabadda, and its has been done in collaboration with Dr. hab Noureddine Bennis and his collaborators at the Faculty of New Technologies and Chemistry of the Military University of Technology, Warsaw (Poland).
