摘要:
In this paper, the reflective and transmissive characteristics of the high-birefringence fiber loop mirror (HiBi-FLM), which is composed of arbitrary lengths and sections of high-birefringence fiber (HBF) were theoretically and experimentally investigated in detail. Simple explicit equations to respectively describe the reflectivity and transmissivity of the HiBi-FLM with one-section, two-section and three-section HBF were obtained, while the process of calculating the reflectivity and transmissivity of HiBi-FLM with n-section HBF was given. The experimental results verified the theoretic model.
