Abstract :
In this paper we propose the use of wavelength as an extra recording dimension by exploiting the plasmonic properties of anisotropic gold nanorods. The wavelength of the longitudinal absorption band can be tuned from the visible to near infrared wavelength region by changing the aspect ratio of the nanorod. Data bits are recorded by femtosecond laser induced reshaping of nanorods in the focal volume. The data can be read out in transmission by monitoring the change in absorption at the recording wavelength.
