Dynamical Hole-Burning Requirements for Frequency Domain Optical Storage.
Abstract
Persistent spectral hole burning (PHB) is a frequency selective bleaching phenomenon that potentially provides a new dimension for optical storage of information, if suitable materials can be found. In the most general form of PHB, narrow depressions or holes are formed (burned) in an inhomogeneously broadened absorption line of an absorber in a solid at low temperatures whenever light absorption causes a change in the absorbing center that persists longer than any excited state lifetime. Previously studied materials involve monophotonic mechanisms for the photochemical or photophysical change leading to hole formation; such mechanisms have serious limitations as to the number of reads that can be performed without distortion of the written data. Recently, photon gated spectral hole burning has been observed in both inorganic and organic materials, indicating that nondestructive reading of spectral holes is possible. This talk will focus on the properties of the organic photon gated material in particular and describe the properties of what might be termed an ideal photon gated system. Keywords: Frequency domain optical storage, Photon gating, Biphotonic, and Nondestructive reading.
