ABSTRACT:
An active optical filter transmits or blocks light according to whether or not a magnetic field is applied, and functions as an optical filter transmitting light having a predetermined wavelength when light is transmitted according to a magnetic field. The active optical filter includes: an optical filter layer for transmitting or blocking light according to whether or not a magnetic field is applied; and a magnetic field applying unit surrounding the optical filter layer for applying a magnetic field to the optical filter layer. The optical filter layer has a multi-layer thin layer structure which is formed of two kinds of thin layers having different respective refractive indices and sequentially and periodically stacked on a substrate.
