Query: High-Q surface electromagnetic wave resonance excitation in
  magneto-photonic crystals for super-sensitive detection of weak light
  absorption in near-IR   Mid-infrared spectrum can be recorded from almost any material making the
mid-infrared spectroscopy an extremely important and widely used sample
characterization and analytical technique. However, sensitivity photoconductive
detectors operate primarily in the near-infrared (NIR) but not in the
mid-infrared making the NIR more favorable for accurate spectral analysis.
Although absorption cross-section of vibrational modes in near-infrared is
orders of magnitude smaller compared to the fundamental vibrations in
mid-infrared, different concepts were proposed to increase the detectability of
weak molecular transitions overtones. Yet, the contribution of magneto-photonic
structures in near-infrared absorption effect has never been explored so far.
Here we propose high-Q magneto-photonic structures for a super-sensitive
detection of weak absorption resonances in near-infrared. We analyze the
contributions of both magnetic and non-magnetic photonic crystal (PC)
configurations to the detection of weak molecular transitions overtones. Our
results constitute an important step towards development of highly sensitive
spectroscopic tools based on high-Q magneto-photonic sensors.
