    Abstract

    In this paper, the spectral analysis of a fourport distributed Bragg reflector-micro ring resonator (DBR-MRR) is studied both analytically and numerically. First, the basic theory of the DBR-MRR is discussed and the effect of DBRs on the resonant mode-split is studied analytically. Then, the theory is supported with a numerical study using the finite difference time domain method. Finally, a potential application of the proposed structure is discussed: a sensor that keeps the concentration of a substance within a desired range; a concentration range controller.
