Singular optics

Singular optics studies the fascinating regions in light fields where properties like phase or polarization become undefined or change abruptly, known as optical singularities. These points or lines, such as phase vortices or polarization singularities, behave like mathematical "twists" or "knots" in the light wave. Understanding these features helps in advanced imaging, communication, and quantum technologies by revealing complex light behaviors and enabling precise control over light's properties. Essentially, singular optics explores these special, often intricate structures within light to unlock new applications and insights into wave behavior.
