optical waveguide

[′äp·tə·kəl ′wāv‚gīd]
(electromagnetism)
A waveguide in which a light-transmitting material such as a glass or plastic fiber is used for transmitting information from point to point at wavelengths somewhere in the ultraviolet, visible-light, or infrared portions of the spectrum. Also known as fiber waveguide; optical-fiber cable.

As the sensors themselves do not need to contain expensive parts and the evaluation electronics can be shared by several cylinders (by using and combining optical waveguides), manageable costs can be achieved.
Therefore, when UV light irradiates the sol-gel thin film through a photomask and the sol-gel film is dissolved in an organic solvent, the UV-irradiated parts remain intact on the substrate and form a patterned optical waveguide with the resolution of 1 to 2 [micro]m.
An LiNb[O.sub.3] optical waveguide of 26.5 mm was used for implementing a photonic filter, which introduced an OPD's of 2.2 mm, in agreement to eq.
Recently, our lab fabricated optical waveguide channels to guide the on-chip light in a more reproducible manner to further improve the sensitivity down to a single-cell level or 1 picogram scale.
Numerous ways of all-optical gates without SOA using length of the fiber, waveguide, circulator, filters, acoustic-optic waves, and changing the refractive index of the optical waveguide have been discussed in the first part.
