Abstract

Digital-phase gratings have groove-shapes in the form of a staircase with typically 4 phase levels. They have a large pitch in the order of 100 p.m, and a block of central diffraction orders is used for light splitting. Properties of such gratings for the appli-cation in wavelength-division-multiplexer are analysed, and experimental results are pre-sented. Reflection gratings are realized on flexible substrates so that one-dimensional concave gratings can be formed for focussing and imaging in "hybrid" planar multiplexers.
