Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by enabling complex ...
Flat optics based on patterned liquid crystals (LCs) has recently received extensive research interest. Comparing with dielectric metasurfaces which are usually fabricated by sophisticated lithography ...
Mini-MOT: A new miniaturized optical system for laser cooling atoms in a magneto-optical trap, or MOT. (Courtesy: NIST) The magneto-optical trap, or MOT, is the workhorse of cold-atom physics. Without ...
