Abstract
An electromagnetic signal processor which uses an inhomogeneously broadened absorbing material to store data for long periods of time and which is able to process an uninterrupted signal. A spectral interference pattern created by the interference of at least two input pulses of electromagnetic radiation is stored in the absorbing medium. The pattern is fixed in the medium to allow for uninterrupted processing of signal data. The fixed pattern employed in such a processor could be reprogrammed by either reversing the gating process used to program the absorbing medium or by spatially directing the electromagnetic beams to a different portion of the material.
