Abstract

In this paper, a new structure of optical filter based on micro-ring resonator (MRR) and Bragg grating is proposed. The micro-ring resonator consists of two linear waveguides, one ring waveguide and two Bragg gratings. The filter has four ports. When optical signal input from one of the four ports, the output optical signals output from other three ports. The spectra of output ports of the optical filter are analyzed by using transmission matrix method. The result shows that the output channels of this optical filter are twice as large as that of the micro-ring resonator without Bragg gratings.
