In this paper the absorption characteristics of Carbon Nanotube(CNT) is determined using CNT samples with varying thickness in the range of 1470-1580nm. The absorption coefficient of carbon nanotube is determined to be equal to ~24 x 104 cm-1. The implications of such strong absorption value are discussed. The different properties Carbon Nanotube (CNT) can be used for various applications. This technologically important material can be loaded into waveguides, by spray coating purified CNT or spin coating CNT or direct PECVD growth, thus allowing the investigation of optical properties such as linear and non linear absorption characteristics, refractive index variation and the characteristics when conjugated with polymer composites. The Carbon Nanotubes (CNTs) were investigated to find the optical absorption coefficient using experimental techniques which were based on the Lambert’s – Bouguer’s law.
