چکیده انگلیسی
In this paper, we study fluid infiltration approach and rod filling technique for dispersion engineering of a photonic crystal fiber (PCF) composed of As2S3-Chalcogenide glass. The numerical results based on finite difference time domain method reveal that when air holes of the innermost ring in a PCF are infiltrated with suitable fluids or filled by glass rods, ultra-flattened near-zero dispersions with high nonlinearities will be achieved over a wide mid-IR wavelength range. The simulations demonstrate that when a 100â¯fs input optical pulse of 20â¯kW peak power and central wavelength of 2.5â¯Î¼m is launched into a 10â¯mm length of the As2S3 PCF filled by PBG-08 rods, a ripple-free spectral broadening as wide as 9â¯Î¼m from 1 to 10â¯Î¼m can be obtained which is used as a suitable source for Mid-IR applications in molecular fingerprint region such as medical diagnosis of diseases, and drug detection.
