Optical filter device for temperature dependence control |
摘要 |
The invention provides an optical filter device which is particularly suitable for compensating the gain produced by an erbium doped fiber amplifier due to temperature variations. The device has a tapered fiber filter mounted on a rigid substrate, such as aluminium, in such a manner that the tapered portion of the filter does not come in contact with the substrate. The fiber of the filter is preferably made of silica.
