Abstract
We propose an optimised fiber design for obtaining spectrally flat, high power supercontinuum (SC) source covering C+L band of optical communication. The design is based on the principle of controlled expansion of SC bandwidth, in the absence of soliton decay, so that a high output power alongwith smooth spectral profile can be achieved. A detailed optimisation has been carried out with respect to fiber dispersion profile, pulse width and fiber length, and the physical mechanism for each case has been emphasised. Numerical simulations show that single mode output with > 30 dBm (± 0.5 dB) optical power is attainable over 90-nm bandwidth with ~ 16 pJ of input pulse energy.
