2-Gb/s ALL-OPTICAL SERIAL DIGITALTO-ANALOG CONVERTER

摘要

A fiber-optic combined serial-to-parallel and digital-to-analog converter is proposed and demonstrated. The system is based on bit interleaving and cross-gain modulation in a semiconductor optical amplifier. The demonstrated 3-bit digital converter operates at 2 Gb/s, however, the proposed architecture could be easily modified to operate at higher bit-rates.
