Abstract
Based on the spectrum waveform similarity (SWS) rule we discovered in periodically poled lithium niobate (PPLN), a compact tunable flat-top bandpass filter is proposed theoretically, from which the bandwidth of the flat-top waveform can be obtained. For practical application, tunable flat-top filter can be easily achieved by selecting appropriate electric field along the transverse direction of PPLN. The tolerance analysis for this kind of tunable flat-top bandpass filter is also presented.
