Chirped multilayer hollow waveguides with broadband transmission.
We show that a genetic algorithm can be used to optimize the layer thicknesses of a hollow waveguide with a multilayer dielectric cladding. It is shown that in such "chirped" hollow waveguide low loss over a wavelength range with more than one octave width can be achieved. We show that dispersion control is possible in such waveguides.
