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 μm, very high reflectivity (>97%), and a low sensitivity to incident angle at the range of −13.8°<θ<+14°. 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.
