Abstract: (3750 Views)
In this paper, we investigate the supercontinuum generation in photonic crystal fibers in the center wavelength of 1310nm which has applications in dental optical coherence tomography (OCT). Supercontinuum generation in a nonlinear photonic crystal fiber (PCF) is simulated by solving the generalized nonlinear Schrödinger equation (GNLSE) using the split-step Fourier (SSF) method. To increase the accuracy of the simulated spectrum, four-order dispersion coefficient, Raman and self steepening effects are considered. Results show that by properly adjusting the input pump parameters such as the peak power and the pulse width, as well as the PCF length, a very wide and smooth supercontinuum is generated which leads to a high-resolution OCT for dental applications.
