A Cascaded Incoherent Spectrum Sliced Transversal Photonic Microwave Filters-An Analysis
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 3
Abstract
An analysis of the performance of a simple, incoherent spectrum sliced microwave photonic filter is presented. This filter structure is based on cascading of two incoherent fiber Fabry -Pérot filters as a slicing element of a broadband optical source. The filter performance is studied by measuring the overall Free Spectral Range, 3dB Bandwidth, Quality factor and Main Lobe to Sidelobe Suppression level for different modes of connecting the filter in cascaded configuration. Also simulation results are presented. The Characteristics of cascaded FP filters with different configurations are tabulated. The estimated performances show that this cascaded filter combination can be tuned over the frequency from 4.6 GHz to 18 GHz with very good sidelobe suppression level.
