Analysis of Nano Opto-Mechanical Tuning of Photonic Crystal Waveguide-Based Device for Pressure Sensing
Lecture Notes in Electrical Engineering(2021)
摘要
A photonic crystal waveguide arranged in hexagonal lattice is proposed which is suspended on silicon slab for sensing applications. The displacement in the PCW slab is investigated with the application of pressure and the waveguide is optimized to obtain high confinement of electromagnetic fields in the core region. The PCW nano-cavity is explored for different applied pressure in the waveguide region. A complete analysis of electro-magnetic field propagation is discussed in detail to obtain high sensitivity in the waveguide region.
