Ultra-high birefringence and nonlinearity photonic crystal fiber with a nanoscale core shaped by an air slot and silicon strips
Optical Fiber Technology(2020)
摘要
•A polarization-maintaining PCF with an air slot and silicon strips is proposed.•Nonlinearity of over 106 W−1 km−1 is derived at 1.55 μm.•An ultrahigh birefringence of ~0.94 at 1.55μm can be obtained.•The low confinement loss of lower than 10−3 dB/km can be achieved.
