Suspended tantalum pentoxide rib waveguides for laser absorption spectroscopy
Suspended tantalum pentoxide rib waveguides for laser absorption spectroscopy
Development of miniature photonic sensors using optical waveguides currently represents an attractive research direction. Owing to more than two decades of research on quantum/interband cascade lasers, laser absorption spectroscopy in the mid-infrared (MIR) domain can be brought to photonic chips. Importantly, the so-called molecular fingerprints, unique molecular absorption spectra, can be addressed in MIR. But waveguides need to adapt for sensing scenarios and one desired feature is a large overlap between the light and the analyte.

Abstract
Development of miniature photonic sensors using optical waveguides currently represents an attractive research direction. Owing to more than two decades of research on quantum/interband cascade lasers, laser absorption spectroscopy in the mid-infrared (MIR) domain can be brought to photonic chips. Importantly, the so-called molecular fingerprints, unique molecular absorption spectra, can be addressed in MIR. But waveguides need to adapt for sensing scenarios and one desired feature is a large overlap between the light and the analyte.
