Conversion of any finite bandwidth optical field into a shape invariant beam
V. Arrizón, F. Soto-Eguibar, D. Sánchez-de-la-Llave +1
We discuss a method to transform any optical field, with finite frequency bandwidth, into a shape invariant beam with transverse scaling, dependent on the propagation distance. The…

Structure invariant wave packets
V. Arrizón, F. Soto-Eguibar, H. M. Moya-Cessa
We show that by adding a quadratic phase to an initial arbitrary wavefunction, its free evolution maintains an invariant structure while it spreads by the action of an squeeze oper…
