Metallic mesh has been widely used in electromagnetic interference windows. While the duty ratio of curved mesh equals to planar mesh'  the theory of planar mesh may be applied to curved mesh according to equivalent-circuit model. So the idea that latitude lines intersect latitude lines to form isometric mesh on the concave of a sphere is put forward  and the method of fabricating the mesh by concentric optical scan is introduced. The movement parts of equipment consist of an erection turning  a horizontal dividing and a pitching dividing spindle. Firstly  a spherical substrate is fixed on the horizontal dividing spindle that has been set horizontally on the erect turning spindle  the substrate revolves around the axis of the erect spindle  the tube of object lens that is fixed on the pitching dividing spindle steps at pitching direction  and a revolving circuit of the substrate corresponds to a step of the tube. Gradually  a set of latitude lines is attained. Afterward  the substrate makes a quarter turn around the horizontal spindle  another orientation latitude lines are also gained. Thus  the isometric mesh on the concave of a spherical substrate is gained. The process comprises surface cleaning  coating photoresist  laser direct writing  development  evaporated film  dissolving photoresist and plating. The fabricated spherical mesh has a line width of 7 m and a period of 600m. Experiment shows that infrared transmission and electromagnetism shield efficiency of the metallic mesh are relatively consistent with theoretical value.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe  which have large nonlinear refractive index coefficients  were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials  thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment  when increasing the power density of control light from 0 to 2.60X105W/cm 2  the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection  optical information processing and optical communication.

Future optical communication systems will use more of the exceptional high bandwidth of optical fiber. Wavelength division multiplexing (WDM) systems are well suited to transport terabits of information via the fiber[1]. Multiplexers/ demultiplexers (MUX/DEMUX) are essential components for dense WDM systems. Several different kinds of multiplexer types have been developed in the past: (a) interference filters  (b) fiber gratings  and (c) planar lightwave circuit (PLC) MUX/DEMUXers[2  3]. The planar fabrication process of the last mentioned PLCs allows the realization of high performance filters with a large number of wavelength channels. Further  an integration with other optical elements seems to be possible. Arrayed waveguide gratings (AWG) are a special kind of PLC-MUX/DEMUXers  which are very attractive components for WDM systems because of their great flexibility in filter design[4  5]. Basically  an AWG is an optical spectrograph built in planar waveguide technique. Typically  AWGs works in a high grating order (50-250). For AWG multiplexer applications in communications systems a precise wavelength controllability and wavelength stability with long term is demanded. Recently  a polymeric (especially fluorinated polymer with low optical absorption loss in the infrared region) AWG has attracted much attention because of its easy fabrication  low cost possibility and a potential of integration with other polymer devices[6]. Standard AWGs  however  show a change of center wavelength with temperature. A method to prevent this temperature drift is to package the AWG together with a temperature controller in order to tune and fix the desired filter-wavelength. In this paper  a 32-channel AWG was fabricated using a cross-linkable fluorinated poly (ether ether ketone) (FPEEK)  its package technology and environmental stability were also discussed. 2005 IEEE.
