Microperiodic structures: Direct writing of three-dimensional webs

Direct Ink Writing of Three-Dimensional Ceramic Structures

The ability to pattern ceramic materials in three dimensions (3D) is critical for structural, functional, and biomedical applications. One facile approach is direct ink writing (DIW), in which 3D structures are built layer-by-layer through the deposition of colloidalor polymer-based inks. This approach allows one to design and rapidly fabricate ceramic materials in complex 3D shapes without the...

Dynamic Analysis of Three Dimensional Asymmetric Isolated Structures

Dynamic Analysis of Three Dimensional Asymmetric Isolated Structures

Three-dimensional imaging of direct-written photonic structures.

Third-harmonic generation microscopy has been used to analyze the morphology of photonic structures created using the femtosecond laser direct-write technique. Three-dimensional waveguide arrays and waveguide-Bragg gratings written in fused-silica and doped phosphate glass were investigated. A sensorless adaptive-optical system was used to correct the optical aberrations occurring in the sample...
