Abstract
In this paper, a comparative analysis of the propagation of double exponential and Gaussian ultra-short pulses in fused-silica core-clad optical fibers has been presented. The present study has taken the non-linear propagation parameters from Schrodinger’s equation and for silica fiber into consideration. The analysis has been carried out for single-mode and multi-mode fibers, to study the effects of variation in pulse parameters and it has been observed that the double-exponential pulses have a bandwidth-efficiency ~23% over Gaussian pulses and may be useful as femtosecond-laser pulse shapes. It is found that double exponential pulses offer more resistance to dispersive effects than Gaussian pulses at longer distances and retain more power levels for higher input powers, while Gaussian pulses continue to decay. Finally, rapid decay in double-exponential pulses may make them suitable for time-and-wavelength-division-multiplexed passive optical networks (TWDM-PON) applications in optical communication.
