Abstract: Abstract We design a three-layer rectangular-groove dielectric transmission grating that can be used as a polarization-selective beam splitter. For TE polarization, the grating is equivalent to a high-efficiency grating. For TM polarization, a good splitting… read more here.

Abstract: The perfect vortex (PV) beam, characterized by carrying orbital angular momentum and a radial electric intensity distribution independent of the topological charge, has important applications in optical communication, particle manipulation, and quantum optics. Conventional methods… read more here.
