Abstract :
An electrooptic analog-to-digital converter which uses a pulsed GaAlAs diode laser for sampling, a LiNbO3Ti-indiffused-waveguide interferometric array for conversion, a Si APD, and a special 1 GHz Si integrated circuit for digital processing has been demonstrated at 1 Gsample/s. Individual bit channels of this 2-bit device have been tested by a beat-frequency technique with a 499.2 MHz test signal. This represents the highest frequency conversion of an analog waveform reported to date.
