Abstract:
1. A photonic crystal combinatorial sensor comprising: an array of photonic crystal materials, wherein, for each photonic crystal material of the array, a periodic difference in refractive indices within the photonic crystal material gives rise to a reflected wavelength in a respective initial wavelength range for that photonic crystal material; the array of photonic crystal materials including at least: a first photonic crystal material configured to have an internal structural response to an external stimulus, the internal structural response resulting in a change in the reflected wavelength of the first photonic crystal material, and a second photonic crystal material configured to have a different response to the external stimulus than the internal structural response of the first photonic crystal material; wherein the difference between the internal structural response of the first photonic crystal and the different response of the second photonic crystal material provides an optically detectable response pattern of reflected wavelengths in the array.
