Silicon Photonic Modulator Achieves 200Gb/s PAM4 Transmission with Low DSP Requirement
Understand the story
A research team from Japan's Institute of Science Tokyo, Yokohama National University, AIST and PETRA published a paper demonstrating a silicon photonic crystal waveguide slow-light modulator with a built-in electro-optic equalizer. The modulator achieves a single-channel 200G/λ PAM4 transmission rate while operating at a low drive voltage, reducing the demand on the DSP. The work remains at the paper-publication stage, with no reports of subsequent volume production or applications.
