.Optimizing design of triplexer chip with low insert loss and high isolation based on planar lightwave circuit[J].Optoelectronics Letters,2007,3(4):251-253 Optimizing design of triplexer chip with low insert loss and high isolation based on planar lightwave circuit CHENSi-xiang XUZhi-guang XIE Hong [1]SchoolofElectro-mechanicEngineering．WuhanUniversityofTechnology,Wuhan430070,China [2]O-NetCommunicationLimited．Shenzhen518957,China Abstract:       Design optimization of a novel integrated triplexer based on planar lightwave circuit (PLC) for fiber-to-the-home applications is described. The two-mode interference coupler and Mach-Zehnder interference are used to construct the filter chip.Simulation results of high isolation and low insertion loss are gotten for proposed design. Technique tolerance is improved for fabricating device. Hits: 3513 Download times: 196 View Full Text    Download reader
