DISPERSIVE OPTICAL DEVICE WITH THREE DIMENSIONAL PHOTONIC CRYSTAL

摘要

The invention relates to a dispersive optical device with a three-dimensional photonic crystal. The object of the invention is to obtain a device having a high damage threshold on the whole and the making of which is facilitated and guaranteeing optimum optical properties. This object is achieved by using a device in silica comprising a three-dimensional photonic crystal and a diffraction grating. This device may notably be used in a compressor system for a short pulse.
