We present a scheme for realizing femtosecond multi-filamentation with designable quantity and locations of filaments, based on the control of multi-focal spots formed by patterned optical fields (POFs) composed of multiple individual optical fields

A low-profile conformal endfire antenna is proposed in this paper. The proposed antenna is a traveling wave antenna, which can be integrated on a curved surface. By changing exciting ports, a forward or backward radiation can be realized. The endfire

We study the nonparaxial propagation behavior of Laguerre–Gaussian (LG) beams under the tight focusing condition by using the Rayleigh–Sommerfeld integrals. We obtain an analytical formula and show the focal shift with respect to the geometric fo

We have presented and demonstrated a method for the fabrication of various complicated microstructures based on dynamically controlled patterned vector optical fields (PVOFs). We design and generate dynamic PVOFs by loading patterned holograms displa

We present a generalized Poincar\'e sphere (G sphere) and generalized Stokes parameters (G parameters), as a geometric representation, which unifies the descriptors of a variety of vector fields. Unlike the standard Poincar\'e sphere, the radial dime

We propose a method to generate the phase-conjugate wave of the vector field by degenerate four-wave mixing in a c-cut Fe-doped LiNbO3 crystal. We demonstrate experimentally that the phase-conjugate wave of the vector field can be generated. In parti

We propose a flexible method to record and reconstruct vector fields with space-variant polarization distribution in c-cut Fe-doped LiNbO3, based on photorefractive two-wave mixing. To our knowledge, this is the first approach for the reconstruction
