Which is better?
Photonic computing offers significant advantages over electronic computing in terms of speed and energy efficiency by utilizing light signals instead of electrical currents for data processing. While electronic computing remains more mature and widely adopted, photonic systems provide higher bandwidth and reduced heat generation, making them ideal for future high-performance applications. However, challenges such as integration with existing silicon-based technologies and the complexity of photonic circuits still limit their widespread implementation compared to electronic counterparts.
Connection
Photonic computing and electronic computing are interconnected through hybrid systems that leverage the speed of light for data transmission while using electronic components for processing and control functions. Photonic components, such as waveguides and modulators, convert electronic signals into optical signals and vice versa, enabling seamless integration between optical and electronic domains. This synergy enhances overall computing performance, reducing latency and power consumption in applications like data centers and communication networks.
