Nowadays, the interface between microwave engineering and photonic technology is used in the field of communication and these new disciplines interdisciplinary approaches are known as microwave photonics (MWP). This article describes various configurations for the microwave photonic filter (MPF) and its application. We study all possible configurations for the MPF and its frequency response and also analyze the spectrum of the laser source used. Say no to plagiarism.

In this technology, the radio signal is transmitted using the photonic device and optical fiber. For these configurations, we use the name MPF. Furthermore, the tunability and reconfigurability of the frequency response require great attention for the researcher. Rof features improvements in reliability, electromagnetic interference (EMI) immunity, wide bandwidth tunability, and low losses. The analog optical link here offers important advantages such as receiver sensitivity and the possible use of analog modulation. Potential applications of analog optical links include antenna remote control, cable television systems, phased array radars, and the interconnection of microwave systems [1]. Different multi-source MPF processes were predicted, including the use of independently tunable laser diodes, broadband optical source spectrum slicing, and the use of a multi-mode Fabry-Prot (FP) laser. This article mainly contains various configurations for MPF which is analyzed and from there what kind of frequency response would get and how this configuration is used for communication purposes. The survey was carried out on methods of providing internet on board, but it did not include new technologies. For MPF we can use different types of optical sources. In this article, we discuss two types of laser diode: 1) multi-wavelength Brillouin-erbium fiber laser (BEFL) and 2) multi-mode laser diode. The use of the multi-wavelength Brillouin-erbium fiber laser MPF is designated and experimentally described in [2]. Figure 1 shows the representation of MPF using BEFL as optical source. BEFL arrangements work with the linear gain of the erbium-doped fiber amplifier (EDFA) and the Brillouin gain in the optical fiber to understand the multi-wavelength lasing effect. By adjusting the pump power, the number of laser channels in BEFL can be easily controlled and used to pump erbium-doped fiber for precise control of optical taps. Since the wavelength spacing of 0.089 nm between adjacent channels is very small in this case, adequate adjustment of filter discernment can thus be achieved. In Figure 1 The BEFL is made up of a standard single-mode fiber (SMF) with a length of 5 km and an EDF with a length of 10 m, confined between two Faraday mirrors. To provide the pumping power to the EDF, a 980 nm laser diode was used. A tunable laser source such as the Brillion Pump (BP) was coupled to the cavity via a 3 dB coupler [2]. Adjusting the EDF pump power adjusts the number of output wavelengths accordingly, while varying the BP wavelength changes the laser output wavelengths. To modify the spectral profile of BEFL, the programmable spectral processor (PSP) is used [2]. THE..
