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.
Yet, most existing setups rely on iterative feedback loops, guzzling computational resources and time. There's a smarter way now. As reported in, a team from Shanghai Jiao Tong University has developed a scattering matrix method that is capable of sculpting light output with minimal optimization time. As a bonus, SM offers insights into the scattering medium's mesoscopic traits, unveiling memory effects and transmission eigenchannels.
Imagine, a carefully orchestrated dance of light—where a matrix row's phase pattern triggers precise nonlinear focus. The result? Sum-frequency generation dances in multiple spots across the region of interest, each with comparable intensity and a remarkable peak-to-background ratio of about 25.
