Integrating 1D Nanostructures in Devices and Circuits for Massively Parallel and Manufacturable Nanoscale Electronics and Photonics

Saif Islam M., Choudhry A., Fong E., University of California Davis, US

A key barrier to wide-scale integration of functional nanowires in devices and systems is the difficulty in forming reproducible and efficient contacts to them. Unlike the research-based approach of sequentially connecting electrodes to individual nanowires [...]

Metal-Semiconductor-Metal Ultraviolet Detectors Utilizing Ge Nanocrystals Active Medium on Si Substrate

Lo S.Y., Wu P.J., Yeh R.H, Hong J.W., National Central University, TW

Since the observation of photoluminescence from porous Si, nanocrystalline Si and Ge have extensively been studied because it would open a possibility for indirect-gap semiconductors for optoelectronic applications. Nayfeh et al. reported ultraviolet (UV) detectors [...]

Engineering the Spectral Response of Waveguide Bragg Gratings Patterned by Deep Ultraviolet Nanolithography

Greiner C.M., Iazikov D., Mossberg T.W., Ticknor A., McGinnis B., LightSmyth Technologies, US

Recent advances in deep ultra-violet (DUV) photolithographic patterning tools have enabled the scribing of essentially arbitrary diffractive structures with feature sizes even below 100 nm that can be precision-placed to within a few nanometers in [...]

Nanotechnology Based Optical Power Control Devices

Donval A., Nemet B., Oron M., Oron R., Oron M., Oron R., Shvartzer R., KiloLambda Technologies Ltd., IL

We are taking advantage of the unique capabilities of nanoparticles guest embedded within dielectric host matrices for field enhancement effect in developing next generation of non-linear components and devices to passively control and regulate optical [...]

Fabrication Process of 3D-photonic crystals via UV-Nanoimprint Lithography

Glinsner T., Lindner P., Mühlberger M., Bergmair I., Schöftner R., Hingerl K., EV Group, AT

UV-based Nanoimprint Lithography (UV-NIL) offers several decisive technical advantages concerning overlay alignment accuracy, simultaneous imprinting of micro- and nanostructures and tool design. A variety of potential applications has been demonstrated by using Nanoimprint Lithography (e.g. [...]
