Abstract

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.

Key words: return link, star coupler, links, distribution ratio, gain
