Design of a Narrowband Photonic Filter Based on the Leaky Outer Defect Mode

Popis výsledku v původním jazyce

This paper presents a novel design of a narrow stopband photonic crystal fiber filter based on the phase matching between the inner fundamental mode and leaky outer defect mode. The significant leakage loss of the outer defect mode is obtained by the reduced diameters of the cladding airholes. Through the investigation of the proposed fiber, it has been found that doping the inner core by germanium dioxide is responsible for the strong confinement of the fundamental mode in the core; significant field transfer to the leaky outer core occurs only in the narrow wavelength spectra making the stopband. Tuning the fiber geometry, the desirable position of the stop-bands can be set as well as the power ratio between the stopand pass-bands. The ratio can be up to 180 dB at the wavelength of 1.55 ?m using the 10 cm long fiber, while the minimum number of airholes and design parameters is ensured. The position of stop-band depends on fiber geometry. We predict that such high sensitivity can be
