Abstract :
In this paper, an effectively single mode reasonably bendable leakage channel fibre is designed having the highly nonlinear As2S3 chalcogenide glass as the fibre background. The fibre is designed to have effective mode area as large as possible as well as to have low confinement loss in the bent fibre. The fibre modal properties are calculated through the finite difference frequency domain method to investigate supercontinuum generation inside the designed fibre. Using the light pump near the zero dispersion wavelength at 4.9 μm, the supercontinuum is numerically observed as nearly flat and broad from 3 to 8 μm.
