Absorption enhancement due to scattering by dipoles into silicon waveguides

Catchpole, K. R.; Pillai, S.

Description

We develop an optical model for absorption enhancement and diffuse reflectance by metal nanoparticles on a siliconwaveguide. A point dipole treatment is used, including the effects of the waveguide on both the angular emission spectrum and scattering cross section of the dipoles. The model agrees very well with our experimental results of greatly enhanced electroluminescence and photocurrent from silicon-on-insulator light-emitting diodes and also gives very good agreement with previously...[Show more]
