  We propose a scheme to enhance the effective photonic bandwidth exploiting
bandgap overlapping of same order or different orders through judiciously
chosen aperiodic geometries is spatial dimension. To implement the scheme, we
design a specialty optical fiber with hybrid chirped-cladding. Our designed
fiber provides an ultra-wide photonic bandwidth of ~ 3 micron. The less
dispersive behavior of the structure carries the signature of zero dispersion
at ~2.7micron. The proposed two material all-solid fiber geometry is based on
thermally compatible chalcogenide glasses, GeAsSe and AsSe as low and high
index respectively. The efficient delivery of short pulses with less
distortion, and enhanced frequency broadening of specific pulses at certain
conditions are demonstrated through these specialty fibers.
