U. Elman et al., INFLUENCE OF LASER PHASE AND FREQUENCY FLUCTUATIONS ON PHOTON-ECHO DATA ERASURE, Journal of the Optical Society of America. B, Optical physics, 13(9), 1996, pp. 1905-1915
Erasure of data stored by use of photon echoes has been investigated a
s a function of data writing time and data storage time. The results c
larify the requirements on laser phase and frequency stability for per
forming photon-echo data erasure. The analysis of phase and frequency
stability of a light source by the photon-echo erasure process is illu
strated. A theoretical analysis emphasizing the physical processes tha
t affect the erasure efficiency as well as an extensive discussion of
possible error sources are given. Finally, an approach to bit-selectiv
e photon-echo data erasure that is insensitive to laser phase and freq
uency fluctuations is suggested. (C) 1996 Optical Society of America.
