| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we propose two types of fiber type polarizers with circular metal regions or circular pit regions on the sides of a circular core. One is a type (denoted 1c3m) in which three metal regions are arranged for one core, and the other is a type (denoted 1c2p1m) in which pits are arranged above and below one metal region for one core. Both 1c3m and 1c2p1m are designed so as to be propagated y-polarization and to be attenuated (disappeared) x-polarization. As a result, when the ratio of the core radius a_1 and the distance d between the core and the metal region (d⁄a_1 ) is designed by changing in the range of 0.3≤d/a_1≤1.4, it is found that 1c2p1m has better characteristics as than 1c3m as a polarizer. In 1c2p1m, at d⁄a_1 =1.4 where the loss $alpha$y of y-polarization is the minimum ($alpha$y = 0.131 dB/cm), the difference $alpha$xy (≜$alpha$x－$alpha$y) between the loss $alpha$x of x-polarization and $alpha$y of 99.81 dB/cm is obtained. Furthermore, it was clarified that $alpha$xy = 314.4 dB/cm can be achieved while keeping $alpha$y of 0.517 dB/cm at d/a_1 = 0.788, which maximizes $alpha$xy. | |
