Abstract | In this paper, a broadband reflector exhibiting a flattened bandstop spectral response is proposed by using a multilayered grating structure possessing multi-subpart profile. It is shown that with the properly configured profile and a strongly modulated grating layer, in transverse electric (TE) polarized wave the presented reflector experimentally demonstrated a 240 nm-wide reflection spectrum from 1.56 to 1.8 mu m, very high reflectivity (> 97%), and a low sensitivity to incident angle at the range of -13.8A degrees <theta <+14A degrees. Effects of deviation from the design parameters on the performance of the reflector are also illustrated, and a reasonably good tolerance of fabrication error is exhibited in the proposed device. |
