Are optical filters active devices

Optical filters are passive optical devices that modify the refractive index of a substrate through specialized optical coatings. The active devices described in this chapter include variable optical attenuators, tunable optical filters, dynamic gain equalizers, optical add/drop multiplexers, polarization controllers, and dispersion compensators. By tweaking the spectral output, these strainers help improve the precision of both imaging and sensing systems. These filters are usually made from plate glass or.
