Researchers from the University of Southampton’s Optoelectronics Research Centre have demonstrated an all-silicon optical modulator at 100 Gb/s and beyond, without the use of digital signal processing. The transmitter nearly doubles the maximum power rate of current state-of-the-art devices. Low-power, low-cost transmitters, such as the Southampton research team’s design, are necessary for overcoming fabrication processes with new materials and those that are not CMOS-compatible.
In addition to in modern communication systems and communication technologies, optical modulation can be used in microwave photonics and chip-scale computing. The new modulator device, according to Ke Li, lead author of the paper describing the…READ MORE
