Optical device having equal length waveguide paths
... Width changes the effective indeX of the Waveguide, chang ing its effective path length; and this effect is different for straight sections and curved sections. HoWever, since the total straight length and total curved length are indepen dently the same for each Waveguide path in the array, the tota ...

The DMCs contain comparable, by number density, amounts of both atomic and molecular Hydrogen, though Table 1.2 further defines these charateristics. Its close to unity extinction means that background radiation can ...
