    • Information Storage

    Background:

    • Frequency-selective optical memory utilizes spectral properties for data storage.
    • Efficient addressing and retrieval are crucial for practical optical memory systems.

    Purpose of the Study:

    • To demonstrate the use of spectral phase codes as storage addresses in optical memory.
    • To achieve rapid data retrieval from spectrally addressed data.

    Main Methods:

    • Engraving data over a 1.5-THz-wide spectral interval.
    • Employing a ferroelectric liquid-crystal modulator for data retrieval.

    Main Results:

    • Successfully utilized spectral phase codes as addresses for optical data storage.
    • Achieved data retrieval in less than 100 microseconds.
