H. Ghafourishiraz et Bsk. Lo, COMPUTATION OF COUPLING COEFFICIENT CONTOURS FOR A 5-LAYER TRAPEZOIDAL GRATING STRUCTURE, Optics and Laser Technology, 26(1), 1994, pp. 45-48
The coupling coefficient contour map of a five-layer slab waveguide st
ructure having a general trapezoidal grating has been computed. Calcul
ations have been carried out for both the first and the second-order B
ragg diffraction gratings.
