Abstract :
An electro-optic analogue-to-digital convertor system has been demonstrated at 1 Gsample/s. This system has been tested with low-frequency waveforms and by means of a beat-frequency technique with a 499 MHz test signal. Digital outputs are slowed in time and then fed into 125 MHz digital-toanalogue convertors which accurately reconstruct the beat signal, proving the compatibility of electra-optic signal processing with digital circuits.
