Successful trials have been made through a designed algorithm to quantize, compress and optically encode unsigned 8 bit integer values in the form of images using nano optical features. The periodicity of the nano scale features (nano gratings) have been designed and investigated both theoretically and experimentally to create distinct states of variation (three on state and one off state). The benefits of using a 4 state unit information carrier is been investigated through transmission models of non ergodic and ergodic signals. A thorough investigation has targeted the effects of the use of multi-varied state nano optical features on data storage density and consequent data transmission rates.
