Photonic crystal structure e.g. for waveguide manufacture has crystalline three-dimensional solid silicon body with a mulitdimensional, periodic empty space

摘要

The structure has crystalline three-dimensional solid silicon body (1) with a mulitdimensional, periodic empty space (6a-6d). The empty spaces have a spherical shape and are in a low pressure atmosphere or vaccuum : An independent claim is also included for the structure manufacturing method.
