Credit: Timur Sabirov/Skoltech Researchers at Skoltech and their colleagues proposed a photonic device from two optical resonators with liquid crystals inside them to study optical properties of this system that can be useful for future generations of optoelectronic and spinoptronic devices. The paper was published in the journal Physical Review B. The simplest kind of optical resonator consists of two mirrors directly opposite each other, squeezing light between them. When you stand inside a mirror resonator, you see infinite copies of yourself in the mirrors; when a liquid crystal - the kind in your computer and smartphone screen - is placed into a much smaller and a bit more complex resonator, interesting things tend to happen. Since the orientation of the liquid crystal molecules can be changed by applying an electric current, researchers were able to control various characteristics of light propagation inside the resonator and, in some sense, simulate the operation of elec
