Silicon Photonic Absorption Methane Spectrometer

Caption

This artistic rendering depicts the new silicon photonic absorption spectrometer, which is smaller than a dime and can be manufactured using high-volume computer chip fabrication techniques. The portion of infrared light protruding outside the waveguide is absorbed by methane molecules, enabling spectroscopic measurement of the methane concentration.
