Abstract
In this paper, we present the theoretical analysis of Bragg waveguide containing a random multilayer defect. Transmittance spectrum of the proposed multilayered cylindrical waveguide is obtained by employing transfer-matrix method. Presence of random defect structure shows multiple defect peaks in the photonic band gap of a defect-free Bragg structure. The probability of occurrence of defect peaks around 660–690 nm is found to be very good, and these peaks may be chosen as a sensing element. Result shows that the transmittance of the defect peak has a good agreement with the change in the refractive index of the core.
