摘要:The invention relates to an optically sampled Analog-to-Digital Convertercomprising an optical source (1) providing radiation of one single wavelength, an electro-optic modulator (4) sampling an analogue signal provided at an electrical input (42), a de-multiplexer (5) de-multiplexing the optically sampled signal, at least one photodetector(7), transimpedance amplifiers (8) amplifying the signals and at least one analogue-to-digital converter (9) converting the analogue signal into a digital signal. The inventionrelates also to a method for using the ADC. One object of the invention is to overcomeproblems in compensating the nonlinearities in the photonic parts and to simplify andreduce the overall cost for optically sampled ADCs. This is solved by a multi wavelengthgenerator (2) and a chromatic dispersion element (3) that provide generating severalwavelengths and delays of the single wavelength radiation of the optical source and thatexcept to the optical source all electrical and photonic components are integrated onone chip.
