✦ Synopsis
In this paper, in regard to the polarization splitter made of two single-core fibers (Fiber 1 and Fiber 2) coupled, the structural parameters and the relationship between the device length and the bandwidth are studied for the xpolarization type and the y-polarization type. In the xpolarization type, the x polarization is taken out from Fiber 1 at the output end and the y polarization from Fiber 2 for the input at Fiber 1. On the other hand, in the y-polarization type, the y polarization is taken out from Fiber 1 at the output end and the x polarization from Fiber 2 for the input at Fiber 1. When the core radius of Fiber 1 is a 1 and that of Fiber 2 is a 2 , the main results for varying a 1 and the core radius ratio a 2 / a 1 are as follows. (1) If a 2 / a 1 is constant, there exists a 1 that minimizes the device length for the x polarization type and for the y-polarization type. (2) For a 2 / a 1 = 1.0, the device lengths of both the x-and ypolarization types. (3) The bandwidths of the x and y polarization types for a 2 / a 1 = 1.0 are somewhat wider than those for a 2 / a 1 = 0.6 and 1.1.
