Title: Polarization- and angle-dependent characteristics in two dimensional photonic crystal membrane reflectors

We report here measured angle- and polarization-dependent reflection properties in two-dimensional photonic crystal broadband membrane reflectors. Polarization independent reflection was obtained at surface normal direction. High reflection can also be obtained for one transverse electric (TE) polarization state over a wide range of incident angles. With the target of 1550 nm spectral band, the measured spectral bandwidths for TE polarization with reflectivity greater than 90% are 180 nm and 56 nm at surface normal and oblique incidence of 45°, respectively. The experimental spectrum approximates the theoretical spectral response of this membrane reflector.
