Subsurface two-photon lithography: improvements and applications
Two-photon lithography has previously been used to fabricate a variety of three-dimensional structures where the material is uniform throughout. When performing subsurface controllable refractive index via beam exposure (SCRIBE), two-photon lithography is implemented with a porous material as the …

Solid state electrochemical processes for nanofabrication
… of the art direct writing techniques (e.g. Ebeam lithography and Focus ion beam lithography). First, a solid state electrochemical direct writing technique is developed using a conductive atomic force microscopy (AFM) tip for rapid prototyping of silver nanostructures on a silver based ion …

Flat optics based on patterned nanostructures for concentrating light
… nanostructured surfaces that are fabricated by two-photon lithography. In the former case, we developed pillar-supported Au bowtie nanoantennas (pBNAs), and found that light concentration in these structures leads to both a large field enhancement and thermal response. We found that intrinsic …

Acoustic Metamaterials at the Microscale
… properties in the megahertz regime. Using a two-photon lithography prototyping method, we explore the response of a class of architected material morphologies with varied mass distribution, features down to ~1.5 µm, and unit cell sizes of 15 µm. We demonstrate that decoupling mass and …

Synthetic Gecko Inspired Dry Adhesive Through Two-Photon Polymerization for Space Applications
… a simplified gecko-inspired microstructure with two-photon polymerization and polymer molding, aimed to improve the adhesive properties of microstructures. Such adhesive microstructures can be implemented for multi-purpose adhesive grasping devices, which have recently gained significant interest …
