A Scheme of Photonic Notch Filter Using DGD Method for Radio-over-Fiber Communication Systems
We demonstrate a scheme of photonic notch filter using differential group delay (DGD) method for radio-over-fiber (RoF) communication systems. It is continuously tunable through adjustment of the central frequency of laser source, capable of achieving lowpass, bandpass or highpass filter. It can be operated in a wide range of optical carrier wavelength. Experimental results show a good notch rejection higher than 20 dB. This scheme could be used in RoF communication systems to reject the channel noise and achieve a better filter performance.
