A new type of Bragg fibers, i.e. hollow-core cobweb-structured optical fibers, which can be used to the low-loss transmis- sion from visible to near infrared region (0.65 μm-1.55 μm), terahertz wave (200 μm-480 μm...A new type of Bragg fibers, i.e. hollow-core cobweb-structured optical fibers, which can be used to the low-loss transmis- sion from visible to near infrared region (0.65 μm-1.55 μm), terahertz wave (200 μm-480 μm) and circular-polariza- tion-maintaining single-mode transmission are investigated. Results show that the hollow-core cobweb-structured fibers have less loss than other hollow-core Bragg fibers. The fibers can be constituted by using the plastics or glasses with large absorption losses.展开更多
