Abstract

The possible application of the spectral hole burning in the optical storage field has attracted scientists’ attention due to its high density storage which increases 3 orders of magnitude more than that of the present conventional optical disk. By adding a frequency space to the optical storage the storage density can break through the limitation exerted by the fight spot diffraction in the three-dimensional space. The holographically optical st

Persistent spectral hole burning [1] in conjunction with holography (PSHB) opens new prospects for high density optical information storage and processing. In the holographic approach, hole burning is carried out with two -crossed coherent laser beams which bleach out a narrow frequency domain hole in an inhomogeneously broadened absorption band recording, at the same time, a spatial holographic fringe pattern. During read out of the hologram diffraction from this spatial fringe pattern occurs, and a holographic image is reconstructed, reflecting the changes of the absorption coefficient and the refractive index introduced by the spectral hole [2].

On Some Problems of Time Domain Data Storage by Spectral Hole Burning

Rein K. Kaarli

Time-and-space-domain holography [1,2] by stimulated photon echoes [3] provides a means of storing temporal and spatial properties of an ultrafast-varying light signal and recalling its authentic replica at any later moment. The possibility of recording complex time shapes of light pulses, which also means time-domain optical data storage, is based on the ability of frequency-selective absorbers to store with high accuracy the temporal Fourier components of the incident light [1-3]. The time-domain frequency-selective optical storage of binary or analog data is an alternative approach to the concept of frequency-selective high-density data storage that provides a parallel ultrafast data storage and processing in the frequency domain. The shortest detail of the signal to be stored is limited by the reverse inhomogeneous bandwidth of the storing media which reaches 10-100 fs for frequency-selective materials while the duration of the signal is limited by phase relaxation time T2 (usually 10-3-10-6s).

Materials for spectral hole-burning storage

W. E. Moerner

One very exciting application of laser spectroscopy would be to use the high-resolution capabilities of today’s lasers and the phenomenon of persistent spectral hole-burning to form a frequency domain optical storage system.1 In such a system, bits of information would be stored by locally modifying (in the frequency domain) the shape of an inhomogeneously broadened absorption line of an absorber in a solid at low temperatures. Because typical homogeneous widths are 1000X (or more) narrower than typical inhomogeneous widths, as many as 1000 bits could be written in one diffraction-limited 1-μm spot In a sample, yielding the impressive storage density of 1011 bits/cm2.

Time Domain Holography

Alexander Rebane

It is acknowledged that inhomogeneous absorption bands consisting of narrow homogeneous zero-phonon lines (ZPL) can be used for the purpose of optical data storage in the frequency dimension /1/. Persistent spectral hole-burning (PSHB) /2,3/ has made it feasible to preserve the recorded frequency domain information for a practically unlimited period of time. Via PSHB the inhomogeneous distribution function of the resonance frequencies of the impurity zero-phonon lines can be altered in an almost arbitrary fashion. This, in turn, makes it possible to manipulate the absorption coefficient and correlated to it index of refraction of the optical storage media. On this basis it has been proposed to use PSHB for the shaping of laser pulses via Fourier synthesis /4/. Holographic storage of time domain optical signals in PSHB media was proposed by Mossberg /5/. In the first experiments on the PSHB time domain holography the reproduction of various temporal shapes of picosecond pulses was demonstrated in dye doped polymers cooled to liquid helium temperature /6/. Earlier Zuikov et al. observed correlation between the temporal shapes of nanosecond excitation laser pulses and photon echo signals /7/. Since that time a variety of experiments on time domain holography in different resonant media have been reported (see /8/ and references therein).

Optical Data Storage Using Persistent Spectral Hole Burning

Eric S. Maniloff, Stefan B. Altner, Stefan Bernet +2 more

The use of holography is attractive for optical data storage due to its poten­tial for implementing page oriented data storage systems. However, multiplexed recording using Bragg selective materials has not provided a large enough stor­age capability to justify the expense of these systems. Persistent spectral hole burning holography allows multiplexed recording using much smaller wavelength separations between the holograms, and hence dramatically increases the storage capacity possible in holographic memory systems [1]. A comparison between the wavelength selectivity obtained for transmission gratings recorded using hole burning in a dye doped polymer film versus Bragg selectivity in a 1 cm thick iron-doped lithium niobate crystal is shown in Fig. (1).

Multiple Photon-Gated Persistent Spectral Holes Burnt over A Whole Absorption Band in A New System of Frequency-Domain Optical Storage Material

You-yuan Zhao, Yong‐Le Pan, Yu Yin +5 more

Persistent spectral hole burning(PSHB) permits use of the frequency domain for achieving ultrahigh-density optical information storage in which the presence of a spectral hole at a particular laser frequency utilized to encode much many bits within a single focused laser spot. The ultimate storage density of the three-dimensional(x,y,f) optical memories can be increased to 109-1011 bits/cm2[1].
