Bypassing the von Neumann Bottleneck via Direct 300-GHz RF Conversion of Optical Computation Results

Electrical computers are widely used; however, their large power consumption remains a major concern. Optical computers, offering high-speed operation with lower power consumption, are an attractive alternative. Nevertheless, the limitation caused by the communication speed between a processor and memory, known as the von Neumann bottleneck, remains unresolved. One way to address this bottleneck is to use wireless signal transmission via electro-magnetic waves, which can greatly enhance the system's flexibility and reduce dependency on high-speed buses where their placement is challenging.
