Check out our new publication, reporting the fabrication of a monolithic all-YAG crystalline microresonator through femtosecond laser nanolithography and thermal annealing, all inside the volume.
Microresonators are one of the most challeging photonic components to fabricate by new methodologies, due the stringent requirements on low-scattering loss and high quality design fidelity.
Once more (see our previous paper on lambda-thin DOEs inside crystals), we demonstrate the extreme potential of our 3D nanolithography technique for novel 3D nanophotonic technology inside solid-state-media.
