| Abstract(in English) | In this paper, we propose a design method of all-fiber bandpass filters based on index-guiding and single-mode photonic crystal fibers (PCFs). This proposed PCF design constitutes a fluorine-doped central core, enlarged air-holes surrounding the central core, and small air-holes in the cladding. It has been predicted from numerical simulations that by varying the design parameters, we can achieve the conditions (short- and long-wavelength cut-offs) where the fundamental mode becomes a leaky-mode, allowing a control on the leakage loss characteristics of the fundamental mode. By tailoring the short- and long-wavelength cut-offs through fiber's structural parameters, doping concentration, and fiber length, we can obtain the desired bandpass filter characteristics. |
