Abstract

We have demonstration of optical comb filter based on the Sagnac loop interferometer of Photonic Crystal Fiber (PCFs). The effect of influence of high birefringence and effect of length of the two sections of the PCFs is analyzed as well as effect of polarization controller on the transmission function. This paper involves the construction of the flat top comb filter. These devices can be applicable for the dense wavelength division multiplexing (DWDM) applications.
