Methods and systems using photonic crystal-based integrated computational elements

A method, comprising:

• selecting a desired transmission spectrum for an integrated computational element (ICE);
• identifying a photonic crystal (PhC) structure having a transmission spectrum comparable to the desired transmission spectrum;
• obtaining the transmission spectrum for the PhC structure;
• determining a predictive power of a PhC-based ICE for a characteristic of a sample with the obtained transmission spectrum and a database of spectra for calibrated samples;
• adjusting the transmission spectrum of the PhC structure to improve the predictive power of the PhC-based ICE;
• and
• fabricating the PhC structure for the PhC-based ICE when the predictive power surpasses a pre-selected threshold.

A computer system comprising:

• a processor;
• and
• a memory device that stores commands executed by the processor to perform a method comprising:
