  • Abstract
    A laminated polarizer is analyzed using the finite-difference time-domain method. An antireflection structure based on a subwavelength grating is introduced to achieve high transmission for the transverse-magnetic wave. As a result, a transmissivity of more than 99% is obtained over a wide wavelength range of 1.0-2.0 μm with almost no transmission for the transverse-electric wave.
