1Productivity
If electrical signal-based channels are used for data transfer between internal devices, then the system can maintain simple architecture and ease of operation, but the bandwidth is limited and power consumption increases
Solution Approach 1:
The patent replaces electrical signal-based transmission with optical signal-based transmission using light emitters and photodetectors. This substitution of transmission medium (from electrical to optical) enables higher bandwidth and lower power consumption by utilizing light properties instead of electrical signals through traditional conductors
Solution Approach 2:
The patent changes the fundamental parameter of signal transmission from electrical domain to optical domain. By using light intensity modulation instead of electrical voltage/current modulation, the system achieves improved bandwidth and energy efficiency characteristics inherent to optical transmission
