Abstract:
A method of producing an all glass, non-porous, multi-component photonic band-gap multiple index array comprising:creating a first photonic band-gap optical fiber by assembling a first preform having a plurality of low refractive index glass rods and a plurality of high refractive index glass rods arranged in a predetermined pattern between the low refractive index glass rods, and heating and drawing the first preform to form a first drawn non-porous subassembly having a first index; creating a second photonic band-gap optical fiber by assembling a second preform having a second plurality of low refractive index glass rods and a plurality of medium refractive index glass rods arranged in a predetermined pattern between the second plurality of low refractive index glass rods, and heating and drawing the second preform to form a second drawn non-porous subassembly having a second index; and assembling a third preform from the first and second drawn non-porous subassemblies, and heating and drawing the third preform to form a non-porous, multi-component photonic band-gap multiple index array.
