A High Efficient Reflector Utilized by a Subwavelength Multi-Subpart Profile Grating Structure
2016
In this study, a high efficient reflector constructed by only a single layer subwavelength grating with multi-subpart profiles is addressed. The properties of the grating reflector are investigated by rigorous coupled-wave analysis. It is shown that for transverse electric (TE) polarized wave, over a broadband spectrum of 1.47 - 2.1 μm, the reflector demonstrates high reflectivity (R0 > 98.5%) and wide angular bandwidth (about 28˚) at 1.8 μm. Effects of deviation from the design parameters on the reflection spectra are also presented.
