4‐bit 828‐megasample/s electro‐optic guided‐wave analog‐to‐digital converter

Individual bit channels of a 4‐bit guided‐wave electro‐optic analog‐to‐digital converter have been demonstrated at 276 and 828 megasamples per second. The converter consists of a mode‐locked Nd: yttrium aluminum garnet (YAG) laser for sampling, a LiNbO3 Ti‐indiffused waveguide interferometric modulator array for conversion, a Ge avalanche photodiode (APD), and a special 1‐GHz Si integrated circuit for digital processing. Beat‐frequency tests with a 413‐MHz test signal, representing the highest frequency analog waveform converted, are reported.
