Single-Bandpass Microwave Photonic Filter With Tuning and Reconfiguration Capabilities

We demonstrate a very simple implementation of a single-bandpass microwave photonic finite-impulse response filter (MPF) with discrete tuning of the bandpass frequency and reconfigurability of the bandpass shape. We also discuss the notion of wavelength sampling in an MPF. A theoretical analysis has been developed to exploit the properties of the proposed MPF.
