PURPOSE: An ultra high frequency optical filter and an ultra high frequency filtering method using the same are provided to generate a multi-wavelength channel filter beam pattern having various wavelength gaps by using a wavelength gap control filter part. CONSTITUTION: An ultra high frequency optical filter includes a light source(100), a wavelength gap control filter part(110), a modulating part(120), and a demodulating part(130). The light source generates an ultra-wideband light. The wavelength gap control filter part generates a multi-wavelength channel filter beam pattern from the light of the light source, and includes an input polariscope, a birefringence optical fiber, a polarization control part, and an output polariscope. The modulating part modulates the multi-wavelength channel filter beam pattern of the wavelength gap control filter part according to an ultra high frequency input signal. The demodulating part generates the ultra high frequency output signal by demodulating the multi-wavelength channel filter beam pattern. |
