Fast random access to frequency-selective optical memories.
Spectral phase codes are used as storage addresses in a frequency-selective optical memory. Data are engraved over a 1.5-THz-wide spectral interval. With the help of a ferroelectric liquid-crystal modulator it takes less than 100 micros to retrieve any spectrally addressed data.
