Development of polarization wavelength characteristic evaluation equipment of polarization maintaining optical fiber coupler

摘要

In the recent surge of needs for high-speed and high-volume data transmission, polarization-maintaining optical fibers (PM fibers) along with polarization maintaining optical fiber couplers (PM fiber couplers) are drawing attention as component devices to be used in the wavelength division multiplexing (WDM) systems especially based on the polarization division multiplexing technique. While the characterization of these devices becoming urgent issue, most of the work, typically done by combining individual measurement equipments, remains very complicated and skill-demanding task. In this report is presented the novel measurement system that enables various characterizations of PM fiber couplers with high throughput and reproducibility, eliminating the complexity involved in handling the separate equipment
