Abstract

Objective: The main objective of this work is to generate the stretched pulses in the time domain at 1550 nm wavelength by using novel Tapered Photonic Crystal Fibers (TPCFs). Methods/Statistical Analysis: In this paper, a new analytical technique known as self-similar scaling analysis is used to obtain exponentially varying Group Velocity Dispersion (GVD) and nonlinear profiles. Results: The outcome of the simulation shows that the sequential stretching factor is strongly reliant on the input pulse width and the propagation distance. We demonstrate the highly stretched distortion less pulses. Applications: The proposed TPCF based stretchers may find attractive applications in ultrafast optical communication and intense power fiber based systems.
