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 to improve localization of the written feature, we have explored single-photon initiation due to its greater control at lower laser power and higher write speed. For example, a milliwatt laser focus translated through the3D volume of a holographic photopolymer writes an optical waveguide with a cross section related to the size, shape, speed and velocity of the laser focus. These variablesallow the waveguide to be arbitrarily routed, tapered and shapedalong its path to implement mode transformations between encapsulated subcomponents. We have also created intererence lithography systems capable of creating large 2Darrays of parallel waveguides and 3D printers that can fabricate arbitrary waveguide arrays layer by layer.
