Impulsive interband excitation with femtosecond near-infrared pulses establishes a plasma
response in intrinsic germanium structures fabricated on a silicon substrate. This direct …

Mid-infrared (MIR) spectroscopy is a powerful tool for characterising the vibrations of
molecular bonds and is therefore ideal for label-free detection of chemical species. Recent …

Based on restricted interferences mechanism in a 1x2 MMI beam splitter, we theoretically
investigate and experimentally demonstrate an ultra-compact MMI-based demultiplexer for …

The many fundamental roto-vibrational resonances of chemical compounds result in strong
absorption lines in the mid-infrared region (λ∼ 2–20 μm). For this reason, mid-infrared …

Plasmonic sensing in the infrared region employs the direct interaction of the vibrational
fingerprints of molecules with the plasmonic resonances, creating surface-enhanced …
