The present invention provides intrinsic units of measure for modeling physical systems. The optical device comprises a waveguide core and a nanocomposite material optically coupled to the waveguide core. Each strip length defines two side portions and a crown portion. Slowing varying phase due to sources other than chemical shift can be removed. The method also includes transferring the reaction product from the growth chamber to the treatment chamber, followed by moistening the reaction product in the treatment chamber, and extracting the moistened reaction product into the atmosphere.
