| Abstract(in English) | A novel photonic functional device, a variable optical filter using dynamic grating in Er doped fiber(EDF)controlled by synthesis of optical coherence function, is proposed, and analyzed.Due to the gain saturation of EDF, a periodic bleaching of the gain(dynamic grating)is generated, when a standing wave is produced by two laser beams traveling in it with opposite directions.When the frequency of the laser is modulated with an appropriate waveform, shape of the coherence function can be synthesized.It can be used to control the interferometric pattern in the fiber, and then the dynamic grating can also be controlled.Thus, the bandwidth of the reflection spectrum of the dynamic grating is adjustable.Simulations indicate that the bandwidth of the filter can be changed. |
