Many storage and processing systems based on spectral holeburning have been proposed that access the broad bandwidth and high dynamic range of spatial-spectral materials, but only recently have practical systems been developed that rival the performance and capabilities of electronic devices. This paper reviews the history of the proposed applications of spectral holeburning and spatial-spectral materials from frequency domain optical memory to microwave photonic signal processing systems. The recent results of a 20 GHz bandwidth high performance spectrum monitoring system with the additional capability of broadband direction finding demonstrate the potential for spatial-spectral systems to be the practical choice for solving demanding signal processing problems in the near future.
