Abstract
We present an extremely efficient rigorous vector electromagnetic analysis of field distribution and power flow in grating coupled surface emitting structures. The developed technique is based on constructing an artificially periodic structure of identical grating coupled device cells separated by anisotropic magnetic/electric perfect matching layers. The resulting periodic multi-layered structure is analyzed using the RCWA combined with a very efficient scattering matrix recursive technique. Calculated distributions of the electric and magnetic field components within the structure as well as the fields coupled into the output regions and into the substrate for typical devices are presented. Field distribution and power flow in the longitudinal and in the transverse directions in the structure are determined for the first time to our knowledge.
