Narrow-band acousto-optical (AO) tunable filter (AOTF)

Tunable Acousto-optical (AO) filters (AOTF) are capable of fast selection of a given signal from other optical signals in a fiber. In modern advanced multiwavelength optical network information is transmitted in a number of independent channels. In particular, these channels are usually positioned at wavelengths in the spectral range from 1530 to 1565 nm. In a typical wavelength division multiplexed (WDM) system, each optical channel is controlled separately because it contains independent data, thus providing multiplexing of the information transmitted along the fiber line. We fabricate narrow-band quasi-collinear AOTF, which can be used in WDM telecommunication systems as well as in acousto-optical spectrometers. The typical features of the AOTF, intended for 1550 nm WDM systems are discribed.

Narrow-band acousto-optical (AO) tunable filter (AOTF) is applicable in areas of research, development, education & production: photonics, optic, laser technology, telecommunications, electronic.
