Photonic bandgap (PBG) regions have been calculated for periodically grooved Si structures, acting as a one-dimensional photonic crystal. The wavelength range of the PBG as a function of the ratio (<i>D</i><sub>Si</sub>/<i>A</i>) is presented, where <i>D</i><sub>Si</sub> is the width of the Si walls and <i>A</i> is the grooved silicon lattice constant. The influence of the parameter <i>D</i><sub>Si</sub>, the refractive index of the space between the Si walls and the number of structure periods, <i>m</i>, on the forming of PBG regions is discussed. A good correlation between the calculated and the experimentally observed PBG regions is obtained.
