Physical optics principles such as interference, diffraction, polarization, and Fresnel equations, and their manifestation in real-world problems.
Engineers at the University of California, San Diego demonstrated a new method for switching magnetic information in a material using specially designed ultrafast laser beams, without an external magnetic field.
Why we recommend it: The original article demonstrates the use of structured light in all-optical magnetic storage, relevant to light-controlled magnetic recording
A team from the State Key Laboratory of Ultra-Intense Laser Science and Technology at the Shanghai Institute of Optics and Fine Mechanics (SIOM) achieved, for the first time, all-optical arbitrary control of chirality and ellipticity in solid-state high harmonics through dynamical symmetry engineering and quantum geometric phase manipulation.
Why we recommend it: The original article presents an all-optical means of controlling solid-state high-harmonic polarization, relevant to circularly polarized attosecond light sources
