Abstract

Tilted Bragg grating (TBG) has been intensively investigated for photonic devices such as fiber sensors and on-chip filters. In this article, we present that TBG can be equivalently realized by designing the tilted sampled Bragg grating (TSBG). As its basic grating is uniform and the sampling structure is in the order of micrometer, the fabrication of TSBG can be realized with one step of holographic exposure combined with micro-lithography. As examples, we designed and simulated the equivalent light responses of the TSBGs in the multimode planar waveguide and single-mode fiber respectively. Moreover, the fabrication tolerance of TSBG has also been analyzed. The proposed technique may pave a new way for different 2D gratings with good design flexibility and easy fabrication in various photonic devices.
