Flexible terahertz wire grid polarizer with high extinction ratio and low loss.
An aluminum-based terahertz (THz) wire grid polarizer is theoretically investigated and experimentally demonstrated on a subwavelength thin flexible and conformal foil of the cyclo-olefin Zeonor polymer. THz time-domain spectroscopy characterization, performed on both flat and curved configurations, reveals a high extinction ratio between 40 and 45 dB in the 0.3-1 THz range and in excess of 30 ...
متن کاملFinite-aperture wire grid polarizers.
The transmission characteristics of wire grid polarizers fabricated in finite apertures are investigated by using a three-dimensional finite-difference time-domain formulation. Specifically, the optical transmissivity and extinction ratio are characterized for a wide variety of geometrical parameters including aperture size in both dimensions, conducting wire fill factor, and polarizer thicknes...
متن کاملGaInN-based light emitting diodes embedded with wire grid polarizers
The use of liquid crystal displays (LCDs) has become prevalent in our modern, technology driven society. We demonstrate a linearly polarized GaInN light-emitting diode (LED) embedded with a wire-grid polarizer (WGP). A derivation of rigorous coupled-wave analysis is given; starting from Maxwell’s equations and finishing by matching the boundary conditions in the grating and other regions of int...
متن کاملWire Polarizers
In 1861 Fizeau studied transmission of polarized light through a screen with subwavelength scratches [1], and in 1888 Hertz performed similar experiments with radio waves and a grid of wires, which transmited polarized electromagnetic waves, of wavelength λ large compared to the wire spacing d, only if the electric field of the wave was perpendicular to the direction of the wires. Explain these...
متن کاملApplication of wire-grid polarizers to projection displays.
We have measured the optical properties of wire-grid polarizers (WGPs). The implications of these results to the application of WGPs in projectors that use reflective light valves are discussed. In particular, the brightness and the contrast ratio of the projection system are investigated as functions of the angle of incidence of the light beam onto the WGP. It was found that the optimal incide...
