Towards High-Quality Polymer/Air-Bragg Micromirrors and Resonators for Photonic Applications

#materials #optics #resonators

Recent developments in additive 3D micro- and nano-printing techniques, such as two-photon lithography (TPL), have paved the way to site-controlled, on-demand construction of complex 3D photonic structures. This has enabled rapid prototyping of required components and tailormade microstructures with sub-micrometer precision and optical quality. In this talk, I present 3D-nanoprinted optical Bragg micromirror configurations for near-IR light [J. Appl. Phys. 134, 123107 (2023)], which are envisaged for use with nanoscale active materials to achieve mechanically tunable Fabry-Pérot resonator modes for tunable light-matter interaction experiments [PSS RRL 15, 2100182 (2021)], e.g., at and around telecom wavelengths. Moreover, the design flexibility and fabrication-based spectral adjustability in a wide range of VIS-to-far-IR wavelengths enable hybrid concepts involving typical optics platforms, such as semiconductor optical structures or fiber tips.
