Abstract

WDM(Wavelength division multiplexing) light wave communication system requires MUX/DeMUX and optical filter OADM can be used to extract and add the specific wavelength channel from the transmission line. In this paper, we propose the OADM based on MZI and cascade FBG. It is able to minimize system and reduce sidelobe. So, we have considered MZI structure and 3dB coupler. Using the coupled mode theory. We also analyze out characteristics of OADM and experiment. From results obtained by experiment and computer. Simulation, the proposed OADM with cascade FBG works well. we hope that the obtained result in this paper con be used as the data to design the OADM with cascade FBG.
