Bright and singular optical 1-soliton solutions of Lakshmanan-Porsezian-Daniel equation with Kerr-law nonlinearity by sine-cosine method

This paper obtains Bright and Singular optical 1-soliton solutions to Lakshmanan-Porsezian-Daniel equation with Kerr-law nonlinearity which models the dynamics of optical soliton propagation through optical fibers. The sine-cosine method has been chosen for obtaining optical 1-soliton solutions of the afore mentioned equation and validity conditions for the existence of the obtained solutions are thereby stated.
