Abstract

For future filter applications, we examine the silicon-based ternary grating SAG (silicon on air on glass) structure. Grating is accomplished by a one-dimensional grating structure composed of ternary periodic structure, where ternary period is realized by combining silicon-air-silicon dioxide layers. The plane wave expansion method (PWE) is utilized to mimic the reflections from such periodic structures. The simulation outcome divulges that the number of layers in the periodic structures have a significant strength on the same. Furthermore, the structure has been tuned for 100% reflection. It is also discovered that the wavelength shift grows steadily from 8 to 32 ternary layers.
