In the intricate world of light, a journey through inhomogeneous media often leads to distortions in space, time, spectrum, and polarization. These distortions, detrimental to applications like optical manipulation, imaging, and communication, have long posed a challenge. Enter the art of wavefront shaping (WS)—a potent tool for correcting these wave maladies in linear optics. But that’s not all. Nonlinearity adds a twist, finding purpose in fields from biological sensing to phototherapy. Now, picture combining these forces—nonlinearity and WS—opening doors to unprecedented control.
