We also discovered that the multihelix waveguide structure produced by twisting a microstructured fibre is the chiral analogue of the 3D Bragg grating. Chiral fibres are fabricated in a miniature ...
Holographic photopolymers can be cast onto and around other optical elements, then patterned with a 3D routed waveguide to form hybrid integrated photonics. While multi-photon initiation can be used ...
