ABSTRACT:
An optoelectronic system is provided for converting analog electrical sigs into digital electrical signals. An optical carrier produced by a laser source is separated into spectral components. An electro-optical modulator modulates the optical carrier with a radio frequency input signal so as to produce an amplitude modulated optical output signal. The optical output signal is then outputted to a wavelength division demultiplexer which separates the output signal into a plurality of separate channels, based on wavelength. Photodetectors connected to each of the channels convert the separated signals into analog electrical signals. These analog electrical signals are outputted to a plurality of standard analog to digital converters which convert the analog electrical signals into digital signals.
