Abstract

The present disclosure provides a gas detection system (100) for detecting target gases having spectral absorption peaks. The system (100) comprises a light source (104), at least three spectral filters (108, SF1-SFn) with each filter having a filtering range corresponding to separate spectral absorption peaks of only one target gas, one or more photodetectors (116, PD1-PDn) to receive light from the light source, and processing circuitry (120). The processing circuitry determines absorption strength of each spectral filter output, compares the absorption strength to the spectral absorption peaks of the target gases, and based on the comparison, determines presence of target gases. The spectral filters may be formed on a substrate using integrated silicon photonics and may have filtering ranges less than 50 nanometers to provide selective detection of gas species.
