Electromagnetic Modeling of Nanooptical 2-D Photonic Crystal Structures in Resonant Micro-Opto-Electro-Mechanical Systems: Polarization Selectivity and Tunability
(2018-08-27)
In this thesis, optical filters and cavities consisting of 2-D Photonic Crystals (PCs) are studied in the Near-Infrared (NIR) range with regard to their optical properties using
the frequency domain 3-D Finite Element Method (FEM). The filter structures are Photonic Crystal Membranes (PCMs) and micromechanically tunable Fabry-Pérot-Filters
(FPFs) with periodically arranged Indium Phosphide (InP)/air elements, which support Guided Resonances (GRs). The focus here is primarily on the polarization selectivity. In

Optical Antennas for Biosensing Applications
(2015-06-19)
The aim of the thesis is to theoretically investigate optical/plasmonic antennas for biosensing applications. The full 3-D numerical electromagnetic simulations have been performed by using finite integration technique (FIT). The electromagnetic properties of surface plasmon polaritons (SPPs) and the localized surface plasmons (LSPs) based devices are studied for sensing purpose. The surface plasmon resonance (SPR) biosensors offer high refractive index sensitivity at a fixed wavelength but are not enough for the ...
