Material for Spectral Hole Burning Storage.

Abstract

Over the awarded period, a new optical laboratory to characterize hole burning materials was completed. Si doped diamond films. Eu3+ and Tu3+ doped polymers and Tu3+ doped sol gel glasses were studied. The diatomic Si2 of the defect center in diamond was established. Low temperature persistent hole burning was observed with hole width of 0.01 cm. Hole width dependence on irradiation dose and temperature were studied. A photoinduced hole filling was observed. A 2D imaging amplitude correlation technique was developed and demonstrated for single shot photon echo read out with a read out speed of 27 Terabits per second. Photon echo dependencies on exposure time, delay time between data and reference pulses, and number of readout cycles were studied. Up to 10,000 single shot readout cycles by a femtosecond pulse were observed without substantial echo signal degradation.
