Abstract
The performance of a polarizing beam splitter based
on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated.
The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave
plates and the high-index half-wave plates with a central defect layer of air. The
linear transmission properties of the polarizing beam splitter are numerically
simulated by the transfer matrix method. The results show that the wavelength
of the polarizing beam splitter can be tuned by adjusting the thickness of the defect
layer of air and the incident angle of light due to the resonant couple of the evanescent
waves localized at the interfaces between neighboring layers.
