Main Article Content
This article presents a structure of the tunable optical demultiplexer using fiber ring resonator incorporating mach-zehnder interferometer. The simulation and the transmission characteristic were analyzed by adjusting the loop length from 0.1 nm to 2.1 nm and adjusting other parameters at appropriate values. It was found that, the loop length at 2.1 nm provided the channel spacing at 0.8 nm and the channel bandwidth at 0.08 nm which could be efficiently applied to optical demultiplexer of Dense Wavelength Division Multiplexing (DWDM) according to ITU-T G.694.1 Standard.
