A system of interlocking blocks and rods or tubes for rapid assembly of component infrastructures, where one or more of those components have electronics, power or other instrumentalities built into the component during manufacture, such as by 3-D printing, and the components thereof and methods therefor. The tool comprises a base structure on which adjuster elements are guided. A reflectionbackscatter of the emitted light is received from an object. The structure is formed by fabricating the layers separately in SOI structure and then bonding them together. The result is that fewer dopant and oxygen atoms exit from the core layers through the free surface during collapse, resulting in fewer defects and lower fiber attenuation.
