Abstract :

---

In this paper, a Fano structure based on Photonic Crystal (PhC) consisting of nanocavities for simultaneously measuring the analyte refractive index and environment temperature is investigated. Compared to the structure of prior sensors, the proposed sensor, in addition to measuring temperature and refractive index, has a Fano output spectrum that improves the detection process. The transmission spectrum of the presented structure is simulated by FDTD method.
