Abstract We propose a plasmonics phase‐shift Bragg grating based on a metal–insulator–semiconductor structure in the wavelength range of 1400–1700 nm. The Bragg grating is formed by a periodic height variation of a semiconductor strip that is separated from a metal surface by a nanoscale insulator layer. Moreover, a phase‐shift structure was introduced in the middle of the Bragg grating. Simulation results demonstrate that the proposed structure exhibits good filtering characteristics with a strong field enhancement. The proposed phase‐shift Bragg grating could be used as an ultracompact filter and enable on‐chip integration of photonic circuits.
