This paper shows that the centeredfractional derivatives introduced by Manuel Duarte Ortigueira in 2006 areuseful in the description of optical solitons. It is shown that we canconstruct a fractional extension of the nonlinear Schrödinger NLS equationwhich incorporates Ortigueira’s derivatives and has soliton solutions. It isalso shown that this fractional NLS equation has a Lagrangian density and canbe derived from a variational principle. Finally, a fractional extension ofNoether’s theorem is formulated to determine the conserved quantitiesassociated to the invariances of the action integral under infinitesimaltransformations.
