Theoretical and experimental investigations of the feasibility of two-photon optical recording in SP-PMMA waveguides for microchannel volumetric storage.

摘要

Since the dawn of the information age, there has been an increasing demand for a higher performance storage system to support data intensive applications. The requirements have been placed on major performance parameters such as capacity, data rate, access time, and cost. Conventional memories based on 2-D surface structures are currently being pushed to their limits. Even then, they can marginally meet with these high demands. At the current growth rate, it is anticipated that the demand of a high performance storage system will outgrow the current memory technology within a short period.; The main area of focus of this dissertation is the investigation of the viability of two-photon optical recording technology to implement a special form of 3-D storage: microchannel volumetric storage. Research work includes architectural system design, material studies, preliminary concept demonstration, theoretical analysis on device performance, and investigation of peripheral devices.; The study indicates that such a storage system is conceivable, and has a potential to overcome certain limitations that currently devitalize 2-D storage systems. However, the implementation of this storage device still requires further investigation and optimization of several parameters such as two-photon material properties and channel characteristics, that govern the architecture of the memory.
