A method and a device for receiving a broadband light pulse modified in the time and frequency domains, the light pulse comprising at least one frequency component. The method comprises receiving the light pulse at a particular moment, separating the frequency components of the light pulse from each other, converting each frequency component into an electrical pulse, performing a first comparison to compare the magnitude of each electrical pulse to a predetermined threshold value, performing a second comparison to compare said electrical pulses exceeding the threshold value at a particular moment, and deciding the bit value in response to the second comparison conducted.
