Abstract

Signal processing functions, such as correlation and Fourier transformation have been performed for signals with 50 MHz bandwidth and 500 TB product. Correlation experiments using Barker and p-n coded signals show the expected sidelobe and compression ratios. To study the effect of the coherency requirement of the light source, both lasers and incoherent sources were used. Experimental results indicate that incoherent light is sufficient for some applications. This opens up the possibility of a completely packaged surface-acousto-optic signal processor with small dimensions. The performance of this processor will be compared with those of other ones, i.e. silicon-on-LiNb0₃ SAW convolver, with respect to dynamic range, TB product etc.
