Abstract
The present invention provides an optical signal shaping device, such as a long period grating, for use with an optical fiber having a core of a first prescribed refractive index n.sub.1 and a cladding of a second prescribed refractive index n.sub.2 and configured to transmit an optical signal therethrough. The optical signal shaping device comprises a long period grating of predetermined length formed within the optical fiber. The long period grating has a nonuniform refractive index profile extending over at least a portion of the predetermined length and is configured to alter the optical signal to produce an asymmetrical optical signal.
