Abstract: An optical structure includes a substrate having semiconductor material and a grating structure. The grating structure has the property of emitting at least one frequency band so that light having a frequency from that frequency band cannot propagate in the grating structure. The grating structure has a configuration of pores and a defective region. The pores are disposed outside the defective region in a periodic array, and the periodic array is disturbed in the defective region. A surface of the grating structure is provided with a conductive layer at least in the vicinity of the defective region. A method for producing the optical structure is also provided.

Abstract: A control device for controlling the printing of at least one web of material in a rotary printing press from a control panel, including an interface system between an operator and individual components of the printing press, further includes an automatic page selector, a memory for storing therein information pertaining to the printing press, products to be printed, control parameters of the individual printing press components, and display parameters of printing process variables, an interrogator for interrogating the memory, and a monitoring/control system for passing on all data to the printing press in order to use a selected component and to modify a variable appertaining thereto.
