Abstract
Aspects of enhanced nanoscale gas chromatography are described. In one embodiment, a nano-scale gas chromatography (GC) module includes a light source, a light detector, and a sensor module having vertically-integrated photonic crystal slab (PCS) Fano resonance filter and GC channel layers. The PCS Fano resonance filter layer includes a hole lattice region, and the GC channel layer comprises a gas channel for separation of analytes in a gas mixture. The gas channel includes a coiled section and an extended length section, where the extended length section extends through a region in the GC channel layer that is stacked in proximity with the hole lattice region. The hole lattice region in the PCS Fano resonance filter layer provides local field enhancement of light generated by the light source for increased light-matter interaction with the analytes in the gas channel.
