The light reflectivity of multiwall carbon nanotubes (MWCNTs) in the 1150nm - 1755 nm wavelength range with pattern-less and pattern-grown nanotubes are studied. From test measurements it concludes that when the multiwall carbon nanotubes are pattern-grown fabricated its return loss is linearly proportional to the nanotubes grown height and consequently the pattern-grown CNTs can be implemented as a good optical attenuator. However for high density nanotubes fabricated with pattern-less process it has greater than 45 dB return loss, this is equivalent to have less than 0.56% reflectivity; with this high absorption effect it can be utilized as a black body absorber.
