Abstract
A hybrid electronic optical chip has a first photonic element with which a first diode is associated, a second photonic element with which a second diode is associated and a common electrical driver connected to the first and second diodes by a common electrical connection with opposite polarity. The electrical driver generates a common electrical drive signal divided in time into first and second drive signal components for independently driving the first and second photonic elements through the common electrical connection.
