Abstract
We examine a multilayered one-dimensional (1D) polarizing photonic crystal designed and fabricated out of a single material. This polarizer is designed for high reflection of the s polarization and low reflection of p polarization at the wavelength of 632.8 nm. This device is fabricated implementing the oblique angle deposition technique to produce six-bilayers of alternating high to low indices of titanium dioxide using e-beam PVD for depositing on top of a fused silica substrate. For modeling, we used transfer-matrix method and numerical finite-difference time-domain analysis to simulate behavior of the 1D photonic bandgap structure. Both model and simulation predict better than 98% reflection for s polarization and less than 1% reflection for p polarization at wavelength of 632.8 nm at an incident angle of 70°. The fabricated device exhibited 94% reflection for s polarization and less than 6% reflection for p polarization at 632.8 nm at an incident angle of 70°. The results are in good agreement with theoretical predictions.
