The purpose of this paper is to design and characterize the Multiplexer/Demultiplexer (Mux/Demux) which uses the concept of coupled mode theory. The design is based on cascading the wavelength selective coupler (WSC) devices utilizing commercial specification. The device is designed on silica substrate with compliance of FTTH wavelength such as wavelengths 1310 nm (upstream data/voice), 1480 nm (downstream...
This paper introduces a new optical device model named as an optical cross add and drop multiplexer (OXADM) which has potential use in CWDM metro area networks. The device uses the concepts of combination of optical add/drop multiplexing and optical cross connect between two main transmission lines in order to implement the wavelength routing operation. MEMS optical switches are integrated in the...

We demonstrate a newly invented device named as optical cross add and drop multiplexer (OXADM) which designed with a combined concept of optical cross connect (OXC) and optical add drop multilexer (OADM). It is designed by improving all drawbacks appear in the previous device with some interesting features added. The OXADM node focuses on providing functionalities of transport, multiplexing, routing,...
This paper describes our recent approach toward advanced optical layer networks through the development of optical cross add and drop multiplexing (OXADM). The OXADM node focuses on providing functionally such as transport, multiplexing, routing, supervision, terminating and survivability in optical layer with ring and mesh topologies. Thus, OXADM is applicable for those networks that have to be migrated...
We designed an innovative frequency multiplexer based on contra-directional coupling and standing-wave resonators within a photonic crystal (PhC) structure. Three add-drop filters were cascaded, and the lattice periods of the PhC strips containing the cavities were changed to tune the dropped frequencies, with a very high degree of freedom. Each filter has a 1 nm bandwidth around 1550 nm and the three...
