Abstract

In a modulation system that modulates and transmits an optical signal over at least one optical fiber in response to an input digital data word of N bits, there is an input enabled for receiving the digital data word; an electrically controllable modulator having one or more waveguide branches, where each branch receives an input of an unmodulated optical signal; and a digital to digital converter enabled for converting the N bits to a digital drive vector corresponding to M drive voltage values, where M>N and N>1. The electrically controllable modulator couples the drive voltage values to the unmodulated optical signal(s). The coupling enables pulse modulation of the unmodulated optical signal(s) thereby generating pulse modulated optical signal(s). The electrically controllable modulator outputs the pulse modulated optical signal(s) to one or more outputs that are enabled for transmitting the pulse modulated optical signal(s) over at least one optical fiber.
