Abstract
A broad band polarization independent reflector working in the telecommunication C+L band is proposed using the guided mode resonance effect of periodic three-level silicon-based element. It is shown from our calculations that this structure can provide high reflection (R>99.8%) and wide angular bandwidth (θ≈8°, R>99.5%) for both TE and TM polarizations over the wide spectrum band 1.5–1.6μm. Furthermore, it is found with Rigorous Coupled Wave Analysis (RCWA) that the extremely wide band property for both TE and TM polarizations is due to the simultaneous excitation of strong modulation guided modes in the design wavelength range.
