We consider the optical properties of semiconductor–insulator and insulator–insulator
nanocomposites, including porous materials such as silicon, gallium phosphide, aluminum …

Porous silicon photonics is the ideal platform for high sensitivity, high selectivity monitoring
of biological molecules in a complex fluidic environment. The potential of this technology …

Photonics is a key technology of this century. The combination of photonics and silicon
technology is of great importance because of the potentiality of coupling electronics and …

We demonstrate record giant birefringence, nearly twice as large as has previously been
achieved (Δ n group= 1.5 over more than 60 nm of bandwidth near λ= 1550 nm) using a …

A femto-and picosecond laser assisted periodic nanostructuring of hydrogenated
amorphous silicon (a-Si: H) is demonstrated. The grating structure with the subwavelength …

A novel class of optical metamaterials is presented consisting of high densities of aligned
gallium phosphide (GaP) nanowires fabricated using metal‐organic vapor phase‐epitaxy …

Giant birefringence is demonstrated in ensembles of randomly grown, vertically aligned
semiconductor nanowires. Bottom-up fabrication of epitaxial semiconductor nanowires …

Strong polarization-sensitive anisotropy of the optical absorption in the visible and infrared
spectral range is observed in porous silicon (PSi) layers formed from bulk (110) Si wafers. It …

Orthorhombic Pb3O2Cl2 (mendipite) nanobelts micrometers in length and tens of
nanometers wide were synthesized by a solventless thermolysis of a single-source …

Porous-silicon (PS) based multilayer periodic structures with photonic bandgaps (PBGs) and
PS single layers that have a strong in-plane birefringence are produced by the …
