Claim 0:
1. An apparatus for gas detection comprising:
a light source, the light source configured to emit light;
an array of air-guided, hollow-core vertical photonic crystal waveguides, wherein the air-guided, hollow-core vertical photonic crystal waveguides of the array of air-guided, hollow-core vertical photonic crystal waveguides are configured to slow and guide the light emitted from the light source within the air-guiding, hollow-cores of the air-guided, hollow-core vertical photonic crystal waveguides of the array of air-guided, hollow-core vertical photonic crystal waveguides; and
a detector array, wherein the detectors of the detector array are configured to measure the intensity of the light passing through each of the air-guided, hollow-core vertical photonic crystal waveguides of the array of air-guided, hollow-core vertical photonic crystal waveguides;
wherein the air-guided, hollow-core vertical photonic crystal waveguides of the array of air-guided, hollow-core vertical photonic crystal waveguides slow and guide light having a wavelength within the absorption bands of the one or more gas species to be detected.
