An Analytical Model to Determine the Optimal System for a Fluorescence Based Multilayered 3D Optical Data Storage System

Abstract

To understand the limitations and capabilities of a fluorescence based three-dimensional optical data storage system, it is essential to perform calculations based on its photothermal mechanism. With this paper, an analytical approach of figuring out the amount of fluorescence attenuation in various layers of a multilayered polymer film by looking at the temperature rise upon illumination with a focused laser pulses shorter than thermal diffusion time of the polymer. The effect of changing the concentration of dye absorbing the laser radiation and the thickness of active layer is explored to provide a pathway for determining the optimum system configuration for a fluorescence based multilayered optical data storage system.
