On-chip devices for absorption spectroscopy and Raman spectroscopy have been
develo** rapidly in the last few years, triggered by the growing availability of compact and …

Optical sensing is an emerging field for photonic microsystems that operate in the mid-
infrared spectral range. In this work we present a photonic gas sensor based on infrared …

Several trace gases such as H2O, CO, CO2, NO, N2O, NO2 and CH4 strongly absorb in the
mid-IR spectral region due to their fundamental rotational and vibrational transitions. In this …

Trace gases such as H2O, CO, CO2, NO, N2O, NO2 and CH4 strongly absorb in the mid-IR
(> 2.5 μm) spectral region due to their fundamental rotational and vibrational transitions …

Photonic sensors that operate in the mid-infrared spectral range are an emerging field for
photonic microsystems. In this paper, we present a photonic gas sensor concept based on …

Hybrid integration of photonic chips with electronic and micromechanical circuits is projected
to bring about miniature, but still highly accurate and reliable, laser spectroscopic sensors …

This paper investigates the use of a miniaturized filter based on a triangular lattice of holes
in a photonic crystal (PhC) slab. The plane wave expansion method (PWE) and finite …

To address the issues of low ratio of evanescent field (γ) and high reflectivity between
waveguide cross‐section and gas for the mid‐infrared waveguide sensors, we propose a …

We investigate the concept of slab Tamm plasmons (STP) in regard to their properties as
resonant absorber or emitter structures in the mid-infrared spectral region. In particular, we …

We have investigated the potential of using the E-field induced birefringence for improving
the sensitivity of uniaxial anisotropic slab waveguide sensor based on evanescent wave …
