Abstract

We report time-domain data storage of as much as 1.6 kbits at a rate of 40 Mbits/s in Eu3+:YOS. Use of a pseudorandom biphase shifting technique to spread the data spectrum proved to be of critical importance in preventing saturation of the transition by the long data pulse train. The experimentally inferred storage capacity, ≳ 5 × 104 bits/spatial spot, plus the competitive single-channel throughput rate, demonstrate the potential of this optical memory.
