Direct-Write Assembly of Three-Dimensional Polyelectrolyte Scaffolds, Inorganic Hybrids, and Photonic Crystals
Photonic crystals composed of a germanium hollow-woodpile architecture are created by replicating 3D microperiodic polymer scaffolds assembled by direct ink writing. First, polymer woodpiles with a face-centered tetragonal geometry are fabricated by direct ink writing. Chemical vapor depositions of …

Tunable Three-Dimensional Photonic Crystal Microwave Resonator with Ultra-Small Mode Volume
… crystal (PhC) cavity (PhCC) based on ABCD woodpile structure. Low material loss of the dielectric and radiation loss suppression of the 3D PhC’s complete bandgap give PhCC high quality factor (𝑄). The design also includes field focusing structure into the PhCC to achieve ultrasmall …

Three-dimensional nanofabrication with elastomeric phase mask
… two-photon (2ph) PnP for producing woodpile polymer structures with high structural quality over large areas, and layouts that quantitatively match expectation based on optics simulations of the process. Depositing silicon into these polymer templates followed by removal of the …

Flexible Fabrication of Multi-scale Integrated 3D Periodic Nanostructures with Phase Mask
… between body centered tetragonal (BCT) and woodpile-like tetragonal (wTTR). The second phase mask consisted of two-layered nanogratings with small sub-wavelength grating periods and phase offset control. That was designed with isotropic properties attractive for generating a complete …

Multinozzle printheads for 3D printing of viscoelastic inks
A high-pressure microfluidic device for 3D extrusion printing of viscoelastic ink was developed. The device was machined out of poly(methylmethacrylate) (PMMA) using a 3-axis CNC mill and contains a bifurcating array of microchannels that split a single stream of ink into 64 streams of equal flow. …
