Review discusses using nonlinear optics with structured light

Light can be tailored, much like cloth, weaving and stitching a pattern into the very fabric of light itself. This so-called structured light allows us to access, harness and exploit all light's degrees of freedom, for seeing smaller in imaging, focusing tighter in microscopy and packing more information into light for classical and quantum communications. In their study published in Opto-Electronic Advances, the authors showcase the recent advances in replacing the traditional linear optical to...
