Carbon dioxide is a vital gas for life on Earth, a waste product of human activities, and widely used in agriculture and industry. Its accurate sensing is therefore of great interest. Optical sensors exploiting the mid-infrared light absorption of CO$_{\mathrm{2}}$ provide high selectivity, but their large size and high cost limit their use. Here, we demonstrate CO$_{\mathrm{2}}$ gas sensing at 4.2 $\mu$m wavelength using an integrated silicon waveguide, featuring a sensitivity to CO$_{\mathrm…
