Simulation Results

We realize high efficiency 0–90[Formula: see text] arbitrary polarization rotation by using a single layer of L-shaped silver hole array inside a silica cube. The simulation results show that the 0–90[Formula: see text] arbitrary polarization rotation can be manipulated easily by adjusting the arm length of L-shaped holes, and the degree of linear polarization (DoLP) of the transmission spectra can achieve high over all range of 0–90[Formula: see text]. Our design has been optimized for 1550 nm wavelength. This arbitrary polarization rotation plasmonic metamaterial may provide more possibilities for applications in photonics.

AbstractUsing an all-fiber mode selective coupler (MSC) at the visible band, here we experimentally demonstrate a generating and wavelength multiplexing scheme for the cylindrical vector (CV) and vortex beams (VBs). The proposed MSCs act as efficient mode converters to produce spectrally insensitive high-order modes (HOMs) at the wavelength ranging from 450 to 980 nm, which have broad operation bandwidth (more than 7 nm), high mode conversion efficiency (94%), and purity (98%), and low insert loss (below 0.5 dB). By adjusting the polarization state and the phase shift of linear polarization (LP)11 mode respectively, the donut-shaped CVs and circular-polarization VBs are achieved. The focused intensity distribution of the donut beam on the cross- and axial-sections is monitored by using a confocal system. The all-fiber solution of producing and multiplexing HOMs opens a new route for stimulated emission depletion microscopy applications.
