Microwave Bandpass Filter Based on Air-Core Photonic Bandgap Fiber Loop Mirror
An all-optical microwave bandpass filter employing air-core photonic bandgap fiber (PBGF) based loop mirror is proposed and experimentally demonstrated. A segment of 20 m air-core PBGF is used in the experiment. The frequency response with negative coefficient is realized and can be tuned by changing the incident optical wavelength because of the wavelength-dependent high-birefringence of PBGF. When the input wavelength varies from 1566 nm to 1584 nm, the differential group delay (DGD) of PBGF changes from 30ps to 110 ps, therefore, the free-spectral range (FSR) of the proposed filter changes correspondingly from 33 GHz to 9.6 GHz
