Electromagnetic wave and lightwave control technologies are fundamental technologies that support our lives, such as optical information processing in optical communications and measurements/tests in factories. Our laboratory mainly studies lightwave control using functional optical materials such as liquid crystals. Specific examples include research on polarization imaging using liquid crystal diffraction gratings and research on nano-order fine processing using special lightwave called optical vortices. We are also engaged in many other studies on electromagnetic waves and lightwaves.This laboratory is the best for everyone who want to study lightwaves, or who like physics (including electromagnetics) or chemistry.
