Paper Abstract

Electro-optic sampling of wideband signals using short duration pulses from a diode laser may offer advantages over the electronic sampling performed in A/D converters. A hybrid optical/electronic A/D conversion technique is described which overcomes some of the difficulties encountered in previous efforts in this area. This hybrid technique uses electrooptic components to perform sampling and time-demultiplexing together with multiple electronic A/D converters. A system which uses 4 parallel electronic A/D converters and a pulsed diode laser is demonstrated with a sample rate of 2 GHz. For single-tone test signals in the range of 10 to 11 Ghz, the precision of this system is as high as 2.8 effective bits, limited principally by laser jitter.
