Abstract
Official abstract text for this publication.
A dispersive optical device with a three-dimensional photonic crystal. The object 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 including a three-dimensional photonic crystal and a diffraction grating. This device may notably be used in a compressor system for a short pulse.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical device for laser pulse compression, comprising: a reflective structure of a three-dimensional photonic crystal having bulk periodicity and including a dielectric material and air or gas; and a reflection diffraction grating included in a dielectric material directly deposited on the reflective structure, the dielectric material of the diffraction grating being the same as the dielectric material included in the three-dimensional photonic c…
