Xu Duan, Xie Hui, Hu Qianggao, et al. Design and test of LC technology-based 1×2 wavelength selective switches[J]. 2008,(6):40-42. DOI: 10.13756/j.gtxyj.2008.06.002.
The Wavelength-Selective Switch(WSS) is a subsystem of the Reconfigurable Optical Add/Drop Multiplexer(ROADM) that is rapidly developing in recent years.It can switch over between any input and output ports
greatly enhancing the networking capability of DWDM equipment.This paper briefly describes the features of several technologies for the realization of WSS
illustrates the structure of the LC-based WSS
presents the specific optical circuit design scheme for the 1×2 WSS
and theoretically analyzes the feasibility of its structure with the help of Jones matrix.
