    "body_text": "Instead of asking a mid-infrared photon to create carriers directly in silicon, the device lets it alter a prepared neodymium optical state and converts that change through a silicon Schottky junction. The reported modulation responsivity is 103 microamps per watt at 6.8 micrometers, with three distinguishable combined-input states. This is a laboratory device demonstration, not a production sensor.",
