| Popis: | A 2D photonic crystal based force sensor using paralleloid ring resonator is proposed and designed for sensing the force. An elastooptic effect method is utilized to analyze the force which persist over photonic crystal. The optical characteristics of paralleloid ring resonator is analyzed and predicted by Finite Difference Time Domain method. A new structure of paralleloid ring resonator is formed by introducing the line defects as waveguide in the design of 2D silicon PC slab in hexagonal lattice with the size of 10µm and 12µm in X and Z direction, respectively. The sensing parameters are observed in the ring resonator which are completely depends on the refractive indices of the material used. Thereby the force can be sensed. The determined sensing parameters such as resonant wavelength is about 1470nm, quality factor is of 145.5 and 100% of transmission efficiency is also achieved. |
