In a semiconductor device (1) for the transmission-reception of modulated optical signals having a semiconductor substrate on which are monolithically integrated a transmitter (4) able to transmit a signal formed by a modulated light carried by a first wavelength, a receiver (6) able to detect a reception signal formed by a modulated light carried by a second wavelength is also provided a sensor (10) of a signal representative of extraneous noise and subtraction means (11, 13, 15) for subtracting from the reception signal a compensation signal formed from the signal representing the extraneous noise detected by the sensor (10). The invention also relates to a process in which the extraneous noise is detected in the vicinity of the receiver and from the signal received by the receiver is subtracted a signal formed from the detected extraneous noise signal.
