Abstract

In this article, a novel microwave photonic filter with negative coefficient using semiconductor optical amplifiers and Fiber Bragg Gratings is proposed. Three major factors, including input current, grating coefficients and the input signal power are analyzed and compared respectively with scrutinize their affects to the filter response. Through the simulation, a better performance of the flat‐top microwave photonic filter can be achieved. Β© 2009 Wiley Periodicals, Inc.

A microwave filter realized by combing a recirculating filter based on a fiber Bragg grating (FBG) resonator and a matched two-arm delay line is presented. The proposed configuration can generate a flexible notch filter with a wide flat-top passband, which overcomes the limitations of the filter-tra

A simple photonic approach is proposed for the implementation of a reconfigurable multi-tap microwave filter with negative coefficients. In this scheme, a dual-optical-input intensity modulation module which can perform counter-phase modulation is constructed using a single electro-optic phase modul

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
