An important field of bone tissue engineering (BTE) concerns the design and fabrication of smart scaffolds capable of inducing cellular interactions and differentiation of osteo-progenitor cells. One of these additives that has gained growing attention is metallic ions as therapeutic agents (MITAs). The specific biological advantage that these ions bring to scaffolds as well as other potential ...

Photonic crystals have demonstrated potential for application in many fields and devices. We demonstrate practical fabrication of three-dimensional photonic crystals using the glancing angle deposition thin film fabrication technique. Optical characterization provides strong evidence for the existence of a complete photonic band gap in three dimensions, centered at 1.6 m. We also investigate th...

We report on ongoing investigations of the potential for Solid Free-form Fabrication (SFF) processes to autonomously manufacture entire fully functional complex electromechanical systems, and of the application of such technology to a selfsustained robot ecology. Two complementary approaches are considered: (a) A universal fabrication system capable of autonomously manufacturing arbitrary machi...

Fused fiber components are the key building blocks that enable reliable and efficient operation of high power fiber lasers. In this paper, we review fabrication techniques for the manufacture of such devices, including mode-field adaptors, fiber tapers, fused couplers, and fused combiners. We present the basic equations governing both the optical performance and fabrication requirements for the...

We present the fabrication of parylene-based hollow nanomechanical resonators, following a simple two step fabrication process with a thermal budget of less than 120°C. This process is ideal for fast prototyping and compatible with most materials used in microand nano-fabrication. In particular, the example we present here shows a hybrid structure with silicon nitride and parylene, but we have ...

In this work we present a new fabrication process that enabled the fabrication of superconducting nanowire single photon detectors SNSPD with fill-factors as high as 88% with gaps between nanowires as small as 12 nm. This fabrication process combined high-resolution electron-beam lithography with photolithography. Although this work was motivated by the potential of increased detection efficien...

An easy and cheap fabrication method for intricate polydimethylsiloxane microfluidic devices is presented. The acrylonitrile butadiene styrene scaffold-removal method uses cheap, off-the-shelf materials and equipment for the fabrication of intricate microfluidic devices. The versatility of the method is proven by the fabrication of 3D multilayer, ship-in-a-bottle, selective heating, sensing, an...

In this paper we focus on the fabrication of individual plastic refractive microlenses with Deep Lithography with Protons (DLP). We give a detailed description of the microlens fabrication technique and the calibration procedure that goes along with it. We highlight the geometrical and optical characteristics of these DLP microlenses and we demonstrate the reproducibility of the fabrication pro...
