Abstract Nanophotonic waveguides are at the core of a great variety of optical sensors. These structures confine light along defined paths on photonic chips and provide light–matter interaction via an evanescent field. However, waveguides still lag

We demonstrate SOI slot waveguides for highly sensitive on-chip detection of methane using tunable diode-laser absorption spectroscopy in the mid-infrared. 1.7 ppm limit of detection has been shown with a 1 cm long slot waveguide.

Chip integrated nanophotonic thin-film waveguides have received a lot of attention in recent years due to a focus on miniaturizing bulk-sized optical devices for mass deployment and low-cost tools [1] . Gas sensing based on thin-film waveguides throu

Nanophotonic devices for optical sensing often display poor evanescent field interaction. We demonstrate a suspended thin-film waveguide with stronger light–analyte interaction than a free-space beam, as verified by detecting acetylene at 2566 nm.

Typical applications of integrated photonics in the mid-infrared (MIR) are different from near-infrared (telecom) range and, in many instances, they involve chemical sensing through MIR spectroscopy. Such applications necessitate tailored designs of
