The interstellar medium (ISM) is the vast expanse of gas and dust that fills the space between stars in galaxies. Comprising a complex mixture of elements, molecules, and particles, the ISM plays a crucial role in the formation and evolution of stars, planets, and galaxies. Understanding the properties and dynamics of the interstellar medium is … Read more
Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption. The new method, developed by a team of scientists, utilizes liquid crystals (LCs) to create holograms that can manipulate the polarization of light at different points. This represents a … Read 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. “Laser writing of waveguides and electro-optical … Read more
