Electro-optical control of polarization in femtosecond-laser written waveguides using an embedded liquid crystal cell

We invite you to read this article Electro-optical control of polarization in femtosecond-laser written waveguides using an embedded liquid crystal cell
This scientific publication introduces a NOVEL APPROACH to embedding adjustable waveplates into FLDW optical circuits. It achieves this by incorporating a layer of liquid crystal into the waveguide. Control over the liquid crystal’s orientation via applied voltage induces bias-dependent phase retardation, effectively acting as a voltage-dependent waveplate.
