title: Al wire-grid polarizer using the s-polarization resonance effect at the 0.8-microm-wavelength band.
abstract: An aluminum wire-grid polarizer whose period is 0.39 microm has been fabricated on a quartz substrate by electron-beam direct-writing lithography and the lift-off method. By using the s -polarization resonance effect and optimizing structural parameters, characteristics such as a loss of less than 20% and an extinction ratio larger than 1000 have been experimentally obtained at the 0.8- microm -wavelength band. Theoretical analysis is performed and found to be consistent with the experimental results.
