Abstract
Current 3D photonic device fabrication approaches can provide sub-wavelength feature sizes, but the ability to include multiple components at any desired location remains a challenge. Here we present an optical positioning and linking (OPAL) platform developed in our lab. It uses optical tweezers and biochemical linker molecules to create nanostructured photonic devices and 3D photonic metamaterials. We demonstrate the assembly of hundreds of microparticles into a 3D structure as well as discuss nanoscale processing speed and accuracy. We have applied OPAL to microtoroid optical resonator chemical gas sensors. Finally, we discuss novel nanophotonic design approaches tailored for compatibility with OPAL.
