Abstract
Abstract A method of producing a passive optical device having optical components including at least one reflection grating, at least one port for polychromatic light and a plurality of ports for monochromatic light. The method includes producing the optical components of the device utilizing X-ray depth lithography so that the grating lines of the reflection grating are parallel to the direction of X-ray radiation emitted as part of the X-ray depth lithography.
