Abstract
We report a new coding technique for the implementation of an electro-optic analog-to-digital (A/D) converter. This coding and A/D conversion can be implemented with an array of tunable, high finesse, channel waveguide Fabry-Perot etalons. Preconfigured dc biases have been shown, on a proton exchanged device on x-cut LiNbO
, to shift the quantized etalon transmission peaks with respect to the applied rf signal voltage necessary for converting analog voltages to digital optical transmissions. Some design considerations for the implementation of the device are discussed.
