      Abstract
      Due to the full reflection of electromagnetic waves, certain frequencies cannot propagate in photonic crystals. Waveguides and resonators obtained by removing some rods in photonic crystals with band gap are sensitive to small changes in refractive index. Using this sensitivity, photonic crystal-based sensors can be designed for different purposes. The refractive index changes when the sample with different refractive index is placed in the detection area.Sensors sensitive to refractive index change, detect samples with different refractive indices placed in the detection area by shifting the resonant wavelength of the sensor. In this study, photonic crystal-based multi-purpose sensor was designed and analyzed by finite element method. The sensitivity and quality factor of the sensors were examined.
