Photonic Crystal Modulator Hits 200G/Channel, But Engineers Question Yield

A Nature Communications paper demonstrates a 320-micron photonic crystal modulator with built-in EO equalization achieving 200G per channel at 26 fJ/bit, but a chip engineer cautions that such devices suffer severe yield and uniformity issues, making them potentially less practical than MRM.
