| Abstract: | In this paper, a novel large scale star coupler is presented for the first time. This star coupler can provide a large number of ports for very large scale single fiber bidirectional WDM network system in future. The WDM star network composed of star couplers has great flexibility of networking. Its size can be increased conveniently and smoothly on line by a factor of m. At the same time, the star coupler is still adapted to the single fiber unidirectional WDM network system being extensively applied nowadays. It provides a good selection for WDM star networks. |
