Optically active Spatial-Spectral (S2) materials are a unique resource for spectrally based optical memory and processing. At cryogenic temperatures, the rare-earth ions in these materials individually exhibit narrow optical resonances on the order of MHz to sub-KHz, but are inhomogeneously broadened over GHz to THz spectral bandwidths providing up to 10^7 resolvable spectral channels. The material...
Spatial-spectral holographic real-time correlative matched filtering of high bandwidth signals is demonstrated. Simple text searches for long phrases in PSK formatted optical data streams at rates up to 100 Gbps are presented.
Spatial-spectral holographic (SSH) materials function as a coherent frequency domain resource for high-performance spectral and correlative processing. Real-time matched filtering of 25 GHz bandwidth signals is demonstrated including simple text searches. Despite cryogenic cooling, SSH processing can be efficient for large scale processing systems.
A broadband signal analyzer that can determine the power spectra and direction of all spectrally non-overlapping emitters for a two antenna system is proposed and demonstrated. A spectrum analyzer (SA) based on spatial-spectral (S2) materials has previously been demonstrated that can monitor broadband signals (over several tens of gigahertz (GHz)) with sub-megahertz (MHz) resolution in real-time (sub-millisecond...
