Moreover, composite gratings can be designed to be selective for specific wavelengths, making them ideal for applications in optical filtering and sensing. A perfect illustration is their use in biosensors, where composite gratings can be engineered to detect specific biomolecules through changes in refractive index. This specificity not only improves detection limits but also minimizes false positives, thus enhancing the reliability of the sensor.

Another area where composite gratings have made significant contributions is in spectroscopy. The ability to resolve complex spectra accurately is paramount in chemical analysis, environmental monitoring, and medical diagnostics. Composite gratings can be engineered to provide higher spectral resolution and sensitivity, enabling scientists to detect even trace amounts of substances. This capability is invaluable for applications such as gas analysis, where identifying specific gases is critical for environmental monitoring and safety.
