title: Extraction of light from sources located inside waveguide grating structures.
abstract: A crossed waveguide grating is presented that can extract the total guided-mode power emitted by a pointsource dipole located in the structure. Results obtained with rigorous numerical simulations are compared with a simple graphic analysis to facilitate an understanding of the far-field radiation pattern of such a luminescent device.
