Design of Tunable Flat-top Bandpass Filter Based on Two Long-period Fiber Gratings and Core Mode Blocker
We propose a tunable flat-top bandpass filter to pass light in a customized wavelength band by using long-period fiber gratings (LPFG) structure. The LPFG structure is composed of a core mode blocker in between two LPFGs. The bandpass spectrum of the proposed structure is obtained in overlapped wave...
