Microwave photonic systems, unlike conventional solutions based only on electronics, can manage large volumes of information. Hence, microwave photonics has turned out to be progressively significant not only as part of 5G cellular networks but also much further.
The main task of microwave photonics is the achievement of narrowband filters: that is, the selection of particular data, at particular frequencies, out of enormous volumes that are transmitted over light.

The continued growth of wireless and cellular data traffic relies heavily on light waves. Microwave photonics is the field of technology that is dedicated to the distribution and processing of electrical information signals using optical means. Compared with traditional solutions based on electronics alone, microwave photonic systems can handle massive amounts of data. Therefore, microwave photonics has become increasingly important as part of 5G cellular networks and beyond. A primary task of microwave photonics is the realization of narrowband filters: the selection of specific data, at specific frequencies, out of immense volumes that are carried over light.
Many microwave photonic systems are built of discrete, separate components and long optical fiber paths. However, the cost, size, power consumption and production volume requirements of advanced networks call for a new generation of microwave photonic systems that are realized on a chip. Integrated microwave photo
