Abstract
A method of producing an all glass, non-porous, multi-component photonic band-gap fiber is provided. The fiber is formed by creating a preform having a plurality of low refractive index glass rods and a plurality of high refractive index glass rods arranged in a pre-determined pattern between the low refractive index glass rods. The preform is heated and drawn to form the non-porous photonic band-gap fiber.
Claims1
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.
