"Revolutionizing Transmitters: Energy Efficiency Achieved with CMOS Chip and Silicon Photonics"
Researchers at the University of Southampton have developed an energy-efficient transmitter based on CMOS technology and silicon photonics. By co-designing the electrical driver amplifier and optical modulator, they achieved high data transmission rates while consuming minimal energy. The transmitter demonstrated a 112 gigabaud-112 gigabits per second on-off keying rate and a 224 gigabit per second pulse-amplitude modulation, with energy efficiency below picojoules per bit. This innovative design approach could inspire the development of similar components to enhance communication technologies.
