Abstract
Spectral hole burning (SHB) allows to extend conventional spatial-domain optical data storage and coherent processing into the dimensions of frequency and time. To achieve ultrafast performance, on the time scale of 10<SUP>-12</SUP> - 10<SUP>-13</SUP>s, we use organic dye-doped polymer materials at liquid-helium temperature. These materials enable SHB recording and coherent transient responses with a broad optical band width of 5 - 10 THz. We discuss applications of organic SHB systems for associative recall of time-and-space domain events, spectral programming of pulse trains, Stark switching of holograms, THz-bit-rate multiplication, cross- spectral processing and photon gated recording of erasure resistant coherent transients.
