In the present paper, the nonlinear response of carbon nanotubes has been investigated by using the dielectric constants of these nanotubes evaluated by using the Maxwell-Garnett Effective Medium Theory. SWNT’s deposited on the tip of a dielectric substrate show a drastic change in reflectance and transmittance of the incident laser light due to change in their nonlinearity and optical constants. This property may be further used for developing all-optical switching devices.
