Electro-Optical Innovation: New Way To Control and Manipulate Optical Signals Developed

The advance could enable the development of compact 3D photonic integrated devices capable of processing large amounts of data and more.
Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable electro-optical control of polarization, which could open new possibilities for chip-based devices and complex photonic circuits based on femtosecond-written waveguides.
