1. An apodizing filter, comprising:
a plurality of subsurface induced scattering centers formed in the apodizing filter,
wherein the plurality of subsurface induced scattering centers scatter light passing through the apodizing filter, and
wherein the apodizing filter is included in a cladding of a portion of an optical fiber,
wherein the portion of the optical fiber comprises a cladding light stripper.
