TLDR
In this paper, a microwave photonic filter that solves the problem of realising a single bandpass RF response is presented, based on using phase modulation together with a pair of gratings, and eliminates the baseband response and periodic spectral response of typical FIR filters.Abstract:
A new microwave photonic filter that solves the problem of realising a single bandpass RF response is presented. The filter is based on using phase modulation together with a pair of gratings, and eliminates the baseband response and periodic spectral response of typical FIR filters. Experimental results demonstrate a single passband square-type bandpass filter response, and operation to high frequencies.read more
