Abstract
Detection of DNA hybridization by Silicon Nanowire Optical Rectangular Waveguide (SNORW) using full vectorial finite element method is presented. Waveguide is designed to detect DNA hybridization through change in refractive index of single strand and double strand DNA. SNORW having high surface to volume ratio with optical confinement inside low index region permits a compact sensor. Waveguide sensing characteristics such as change in effective refractive index, waveguide sensitivity and power confinement is evaluated for optimized silicon wired waveguide.
