| The microwave photonic can be considered as the study of opto-electronic devices and systems processing signals at microwave frequencies. The key advantages of microwave photonic links over conventional electrical transmission systems, such as coaxial cables and waveguides, include reduced size, weight and cost, low and constant attenuation over the entire microwave modulation frequency range, immunity to electromagnetic interference, low dispersion and high-data transfer capacity. The weight and attenuation bene efits of microwave photonic links over coaxial cables are particularly compelling: typically 1.7 kg/km and 0.5 dB/km for the fiber with 567 kg/km and 360 dB/km at 2 GHz for a coaxial cable. Research activity in microwave photonic techniques has focused on the photonic distribution of microwave signals, the photonic processing of microwave signals, the photonic generation of microwave signals and the photonic analog-to-digital conversion. This research is developed taking into account the photonic distribution and processing of microwave signals using a microwave photonic filter. A microwave photonic filter is a photonic subsystem designed with the aim of carrying equivalent tasks to those of an ordinary microwave filter within a Radio Frequency (RF) system, bringing supplementary advantages inherent to photonics, and also providing features which are very difficult or even impossible to achieve with traditional technologies, such as fast tunability and reconfigurability. In literature, several architectures of microwave photonic filters have been proposed. However, we use a simple and easy implementation microwave photonic filter architecture which consists of a multimode laser diode, a Mach-Zehnder intensity modulator, an optical fiber, and a photodetector. The radio frequency to optical conversion is achieved by externally modulating the optical source. The RF signal is conveyed by an optical carrier and the composite signal is injected to an optical fiber. At the fiber output, the resulting signal is optical to radio frequency converted by a photo-detector. The frequency response of this microwave photonic filter is constituted of a series of microwave band-pass windows and it depends on the parameters such as the electrical frequency of the signal injected to the Mach-Zehnder modulator, the fiber chromatic dispersion, the fiber length and the Fourier transform of spectral density of the optical source used. | |
