Yang Junfeng, Sun Liping, Yuan Zhilin, et al. A novel liquid crystal technology-based 2×4 flex-grid WSC[J]. 2015,(3):50-53. DOI: 10.13756/j.gtxyj.2015.03.017.
This paper presents the structural design of a novel liquid crystal technology-based Wavelength Selective Cross-Connect(WSC)
which realizes 2×4flex-grid WSC by means of polarization multiplexing on the basis of the conventional 1×N WSC
thus reducing the number of the devices required for system networking
improving the system integration level and lowering the networking cost.Theoretical analysis and experimental results verify that total insertion loss of this WSC is less than5 dB and the 3dB bandwidth of 50 GHz grid in operating state is greater than 40 GHz.
