Abstract
Optical 30-symbol quadriphase-shift keyed (QPSK) and binary-phase-shift key ed (BPSK) codes were processed in a spatial-spectral holographic correlator with the Er3+:Y2SiO5 spectral hole-burning material operating at 1536 nm i n the important 1550-nm communications band. The results demonstrate the ab ility of spatial-spectral holographic correlators to process QPSK codes and BPSK codes with the same apparatus. The high-fidelity correlations produce d by this optical coherent transient device exhibit the low sidelobe charac teristics expected for the codes used. (C) 2000 Optical Society of America.
