A surprisingly simple technique based on physical phenomena first described more than a century ago could provide a new and highly controllable means of producing complex three-dimensional polymer ...

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 ...

Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...
