    "summary": "A hierarchical transformation addressed arbitrary supermodes and carried an aggregate 1.2 terabits per second in a silicon demonstration.",
    "body_text": "The reported design uses a second-order discrete supersymmetric transformation to excite and extract selected supermodes while preserving large, even index spacing. Six-mode multiplexers built on silicon and silicon nitride showed insertion losses below 2.6 decibels and crosstalk below minus 11.1 decibels over 100 nanometers. A silicon device transmitted an aggregate 1.2 terabits per second below the stated error-correction threshold.",
