optical mode

optical mode

[′äp·tə·kəl ‚mōd]
(solid-state physics)
A type of vibration of a crystal lattice whose frequency varies with wave number only over a limited range, and in which neighboring atoms or molecules in different sublattices move in opposition to each other.

In addition to optical mode conversion, FiberPlex offers fiber optic products for affordably increasing the capacity of existing fiber optic infrastructure.
The last expressions in (6) and (7) account for the dispersion properties giving the mode with cut-off or the optical mode, respectively, while no acoustical one exists.
When deploying an all-fiber network, there are three types of optical mode (OM), multimode fiber that are designed for vertical and horizontal usage: OM1, which is 62.
For example, owing to the enhanced light-vapour interaction and the small volume of the optical mode, it allows to explore few photons-few atoms interactions, with the ultimate goal of demonstrating effects in the single photon level regime.
