We demonstrate a compact (1.2 mm^2) fully integrated room-temperature mid-infrared spectrometer operating at ~3.8 μm. To our knowledge this is the longest wavelength integrated spectrometer working in the important wavelength window for hydrocarbon- and organic compounds spectroscopy. The spectrometer is based on a Silicon-On-Insulator (SOI) Arrayed Waveguide Grating (AWG) filter. An array of InAs(0.91)Sb(0.09) p-i-n photodiodes is heterogeneously integrated on the spectrometer’s output grating couplers using adhesive bonding.
