The paper presents a general-purpose photonic processor designed to integrate silicon photonics with electronic and software layers, enabling advanced radiofrequency applications. This processor leverages the unique properties of photonics, such as ultra-high bandwidth, high-speed operation, and low power consumption, to complement electronic processors. The processor can implement various functionalities, including reconfigurable filtering, frequency conversion, arbitrary waveform generation, and beamforming, which are currently provided by microwave photonic subsystems in next-generation 5/6G wireless systems. The processor is fabricated in a silicon photonics platform and includes a reconfigurable core of 72 Programmable Unit Cells (PUCs) distributed in a flattened hexagonal mesh topology. It also features an optoelectronic monitoring unit array and high-performance filters. The processor's operation is controlled by an electronic layer with phase actuators and photodetectors, and it is programmed through a software layer. The paper demonstrates the processor's capability to implement all the main functionalities required in microwave photonic systems, including tunable and reconfigurable filters, optical generation of millimeter-wave signals, arbitrary RF waveform generation, tunable delay lines, beamforming, 5G signal interconnection and power division, frequency measurement, and optoelectronic oscillation. The processor operates in the 15 to 45 GHz band and can be scaled to higher frequencies by reducing the Basic Unit Length (BUL). The paper highlights the benefits of the general-purpose architecture, including reduced costs, increased flexibility, and improved performance compared to application-specific integrated circuits (ASICs).The paper presents a general-purpose photonic processor designed to integrate silicon photonics with electronic and software layers, enabling advanced radiofrequency applications.
