【Abstract】 In this article, two optical isolators are reported. The operation principle of the polarization independent isolator and the miniature freespace isolator are described. The insertion loss, isolation, return loss, polarization dependent loss (PDL) of the isolators are discussed. The specificities of the isolators are compared with that of the same kind products internationally.更多还原
