AI Article Synopsis
- A novel 19-cell hollow-core photonic bandgap fiber (HC-PBGF) is designed with a hybrid structure for polarization maintenance and improved performance.
- The introduction of six anti-resonant tubes allows for robust single-mode functionality, while adding silicon layers enhances birefringence to a remarkable level of 10.
- This innovative fiber achieves a higher-order mode extinction ratio (HOMER) greater than 4.71 × 10, and maintains its single-mode, high birefringence capabilities in the 1530 nm to 1595 nm waveband, even when bent tightly to a radius of 5 mm.
Article Abstract
A novel-hybrid structure polarization-maintaining 19-cell hollow-core photonic bandgap fiber (HC-PBGF) is proposed. Robust single-mode characteristic is achieved by introducing six anti-resonant tubes into the core of 19-cell HC-PBGF. A high birefringence at the level of 10 is achieved by adding silicon layers into the y-direction tubes. The higher-order mode extinction ratio (HOMER) is greater than 4.71 × 10, and the high birefringence can be improved to 5 × 10. In the waveband from 1530 nm to 1595 nm, the single-mode, high birefringence performance can be effectively maintained even under a tight bending radius of 5 mm.
