Abstract:
1. A circuit for converting a digital input data word having a plurality of bits into a modulated signal, comprising: (a) an electrically controllable device, having a plurality of actuating electrodes, and operatively connected to an optical output port, the electrically controllable device providing at the output port an optical signal that is modulated in response to a binary actuation vector having a plurality of binary electrode-actuation voltages applied as electrode-actuation voltages to the actuating electrodes; wherein a number of said actuating electrodes is larger than a number of bits in the digital input data word; and (b) an electrode actuating device having an electronic input for receiving the digital input data word and a digital-to-digital converter, said electrode actuating device respectively supplying the plurality of binary electrode-actuation voltages to the plurality of actuating electrodes; wherein the digital-to-digital converter is enabled for presenting said binary actuation vector to the plurality of actuating electrodes of the electrically controllable device to represent digital input data word.
