Optical nanofiber stretcher

Optics Letters, 2023
Piezoelectric stretching of optical fiber is a technique that enables the creation of optical delays of a few picoseconds; this is useful in a variety of applications in interferometry or optical cavities. Most commercial fiber stretchers involve lengths of fiber of a few tens of meters.

Nanofibers

Advanced Materials, 1997
The preparation of nanofibers—fibers with nanometer diameters—is briefly reviewed. Particular attention is paid to the synthesis based on locking‐in the mesophasic structures formed by diblock copolymers. Examples of the resulting nanofibers with a core‐shell structure (prepared for transmission electron microscopy by a freeze‐drying method) are shown ...

Nanofiber Frequency Doublers

Nano Letters, 2006
Nanoscaled, needle-shaped frequency doublers have been generated via self-assembled surface growth from functionalized quaterphenylene molecules with a designed large hyperpolarizability. The nanofiber frequency doublers exhibit very weak fluorescence centered around 430 nm but emit a strong, resonance-enhanced second-harmonic signal when excited with ...

Continuous Carbon Nanofibers For Nanofiber Composites

MRS Proceedings, 2001
ABSTRACTContinuous carbon nanofibers were manufactured using electrospinning technique. The as-spun polyacrylonitrile (PAN) nanofibers were stabilized and carbonized to convert them into carbon nanofibers. The diameters of typical carbon nanofibers were in the range from 100 -500 nanometers.

Nanofiber Patent Landscape

Recent Patents on Nanotechnology, 2007
Despite the large number of publications in peer review literature in the field of nanofibers, there is still uncertainty as to what aspects of these research results have commercial applications. In an effort to better understand the technological progress made in the field of nanofibers, we surveyed the patents issued in the United States from 1976 ...
