Abstract

The invention relates to an optically sampled Analog-to-Digital Converter comprising 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 invention relates also to a method for using the ADC. One object of the invention is to overcome problems in compensating the nonlinearities in the photonic parts and to simplify and reduce the overall cost for optically sampled ADCs. This is solved by a multi wavelength generator (2) and a chromatic dispersion element (3) that provide generating several wavelengths and delays of the single wavelength radiation of the optical source and that except to the optical source all electrical and photonic components are integrated on one chip.
