Optimization of reflectance based on SAG Structure using Plane Wave Expansion
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 …

Understanding of optical power in semiconductor based SOI Structure at the signal 1550 nm
Abstract: A silicon-on-insulator (SOI) structure consists of a single crystalline silicon layer separated from the bulk substrate by a thin insulator layer. The insulator in SOI wafers is usually always a thermal silicon oxide (SiO2) layer, with a silicon wafer as the substrate. The silicon sheet can be very thin (50 nm for fully depleted transistors) or tens of micrometres thick, depending on the application. Similarly, the thickness of buried oxide …
