Abstract: Methods and systems for encoding multi-level pulse amplitude modulated signals using integrated optoelectronics are disclosed and may include generating generating a multi-level, amplitude-modulated optical signal utilizing an optical modulator driven by two or more of a plurality of electrical input signals. The optical modulator may configure levels in the multi-level amplitude modulated optical signal. Drivers may be coupled to the optical modulator, and the plurality of electrical input signals may be synchronized before being communicated to said drivers. Two or more of said plurality of electrical input signals may be selected utilizing one or more multiplexers. The one or more multiplexers may select an electrical input or a complement of the electrical input. Phase addition may be synchronized in a plurality of optical modulator elements in the optical modulator utilizing one or more electrical delay lines. The optical modulator may be integrated on a single substrate.
