Deep notch filter based on liquid-filled photonic crystal fiber
摘要
Abstract
A deep notch filter in a liquid-filled photonic bandgap fiber (PBGF) realized via filling an erbium-doped solid core photonic crystal fiber with high-index liquid is proposed and demonstrated. The numerical investigation indicates that the notch is formed due to avoid-crossing effect between the fundamental mode and LP02 supermodes. The resonance wavelength of the filter can be tuned by adjusting the temperature of the liquid-filled PBGF and shifts toward short wavelength. The blue-shift speed average is 1.3 nm/°C.
