Who needs a single glass material ?

Hollow optical fibres based on antiresonance can be made with different materials at the core boundary!!! The antiresonance mechanism takes please anyway, in a comparable way to what happens in a conventional hollow antiresonant fiber !!! This apply to fibers covered with semiconductor (white lines in the left picture) but it would  apply also to more complex structures.
Overall all of these structures can be thought like equivalent to a single material fibre with the right thickness and refractive index.
I will present these results soon in Rochester (USA) at the Frontiers in Optics Conference. Link
