Highly sensitive simultaneous measurement of refractive index and its changes using a photonic crystal biosensor with coupled resonators
The paper proposes a novel optical sensor based on one-dimensional binary (SiO2/Si) photonic crystals (PC) with two defect layers to measure the refractive index of the sensing analyte directly and in real-time. Two coupled modes are observed in the bandgap of the PC which is affected by the defect...
