Optical beam propagation inside a graded-index fiber with saturable nonlinearity
Tiyas Das, Anuj P. Lara, Samudra Roy +1
We study theoretically the spatial evolution of optical beams inside a graded-index fiber exhibiting saturable nonlinearity. Utilizing an approach based on the variational principl…
