Abstract:
1. A photonic bandgap fiber (PBGF) for propagating light having a wavelength, λ, said fiber comprising: a core; and a cladding disposed about said core, wherein said cladding comprises a plurality of regions, at least one region having a dimension, Λ, and is configured such that the cladding at least partially surrounds a hole having a hole dimension, D, wherein said plurality of regions are arranged as a rectangular lattice, wherein said portions of said cladding form webs and nodes of said lattice such that at least a portion of said webs have a dimension, d wherein a portion of the webs are connected to said nodes, at least a portion of said nodes having a dimension, d wherein D/Λ is in a range from about 0.9 to about 0.995 and said PBGF is configured such that a relative wavelength transmission window Δλ/λc is larger than about 0.35.
