Exhibiting Dispersive Characteristics at 1330 nm for Optical Pulse Propagation through 2D Kerr Nonlinear Medium

Finite Difference Time Domain (FDTD) method is utilized for modeling the optical pulse propagation in two-dimensional Kerr nonlinear dispersive medium. Through our investigation, spacio-temporal propagation owing to the nonlinear effect is exhibited through modal analysis; and corresponding pulse broadening effects are displayed as a combined result of temporal dispersion and spatial diffraction. Simulation is carried out using opti-FDTD software. 1330 nm wavelength is considered for the present study, which is theoretically distortionless; however, still demonstrate the dispersive nature owing to the Kerr effect. With high intensity pumping, both TE and TM modes are plotted along with the computation for energy flow. Results are important for designing aperiodic lens and for optical switching.
