Wavelength Separation Add/drop Mu Multiplexer with the Various Network Topology

다양한 망구현이 가능한 파장분리형 광 애드/드롭 다중화기

We Propose a novel structure add/drop multiplexer based on an all-fiber Mach-Zehnder interferometer and fiber Bragg grating. In this structure, wavelength separation is achieved by adjusting the amount of the phase shift in the Mach-Zehnder interferometer. The proposed add/drop multiplexer drops a part of signal at a specific wavelength and transmit the remnant of the signal to the different node separated wavelength in WDM network.
