Microwave Photonic Filter: A Systematic Literature Review

Abstract

An overview of microwave photonic filters which are implemented in both incoherent and coherent operational regimes has been provided. For microwave photonic filters implemented in the incoherent regime, an incoherence light source usually a broadband light source such as a light-emitting diode source, an amplified spontaneous emission source, or a laser array is needed. Importance of negative coefficients and complex coefficients in photonic FIR filters is discussed in detail. In this paper various technique reported in the last few year for both incoherent and coherent regime microwave photonic filter are reviewed with significance on the system architecture of microwave photonic filters , photonic generation , processing of time-delay microwave photonic signals, tunable and reconfigurable microwave photonic filters. Complexity and challenges in system implementation for widespread use for practical application and possibilities of newer research in microwave photonic were also discussed.

Demonstration of a Duplex Microwave Photonic Filter and Its Reconfigurability in a Frequency Range of 0–10 GHz

“…A microwave photonic filter (MPF) is defined as a photonic system designed for carrying out equivalent tasks to those of an ordinary electrical microwave filter within a radio frequency (RF) system. An MPF provides benefits innate to photonics, such as low loss, high bandwidth, immunity to electromagnetic interference (EMI), tunability, and reconfigurability [1][2][3]. These benefits make them a technology whose main application is to assign frequency bands; as a consequence, one of its applications is in the field of optical communications.…”
