This paper presents triangular core fiber for single-mode operation. The fiber supports single mode at a wavelength of 1550- nm, and it has an extremely large mode area of 2000 μm2. With peak power of 85.4-kW at 1550 nm wavelength, fiber design demonstrates undistorted delivery of 100 fs laser pulses. We have used Transfer matrix method to analyse the fiber. The splitstep Fourier method has been used to solve the non-linear Schrodinger equation. Raman’s response and self-steepening have also been taken in to account. In this paper, we report the numerical demonstration of propagation of 100-fs pulse with peak power of 85.4-kW at 1550-nm wavelength through 2.5 m long fiber. The ratio of dispersion length to nonlinear length has been kept as 1 for the delivery of undistorted pulses. |
