摘要: Long term optical memory includes a storage medium composed from an array of silicon nanoridges positioned onto the fused silica glass. The array has first and second polarization contrast corresponding to different phase of silicon. The first polarization contrast results from amorphous phase of silicon and the second polarization contrast results from crystalline phase of silicon. The first and second polarization states are spatially distributed over plurality of localized data areas of the storage medium.

摘要: An optical device may include, in order, a first quarter wave plate; a half mirror; a second quarter wave plate; and a curved nanowire grid polarizer. The curved nanowire grid polarizer may include a curved substrate, a non-regular, substantially periodic array of substantially parallel, elongated nanoridges disposed on the curved substrate and having a wave-ordered structure and being oriented along a first direction, and an array of metal nanowires disposed on the array of nanoridges

摘要: An array of nanowires with a period smaller than 150 nm on the surface of curved transparent substrate can be used for applications such as optical polarizers. A curved hard nanomask can be used to manufacture such structures. This nanomask includes a substantially periodic array of substantially parallel elongated elements having a wavelike cross-section. The fabrication method of the nanomask uses ion beams.
