Reconfigurable Millimeter-Wave Photonic Filter Based on Spectrum Slicing by Cascaded Fabry-Perot Filters

Authors : R.K. Jeyachitra and J. Martin Leo Manickam

Abstract: Researchers propose and develop a simple and new reconfigurable millimeter-wave photonic transversal filter featuring high quality windowing property. The filter design is based on spectrum slicing of a broadband optical source by two cascaded fabry-perot filters. It shows the overall filter passband frequency response at millemeterwave band. This is obtained by properly choosing different free spectral range of two fabry-perot filters in cascaded configuration. The simulated results are presented to show that the overall filter free spectral range is 41.1 GHz. The 3 dB bandwidth is 50 MHz. It shows excellent side lobe suppression. A high quality factor of 822 has been reported. Reconfigurability of the filter is achieved by employing multiple apodization profile with two fabry-perot filters in cascaded form. The reconfigured frequency response of the filter is demonstrated for different windowing profiles and the results are tabulated. The results show high quality response of the filter. The advantage of this configuration is that a high performance filter is obtained without the need of any suppression of passband RF-spectral distortion which makes the system as simple and cost effective. It can be used for high density telecommunication networks and millemeterwave photonic communication systems.
