1. A method for processing signals, the method comprising:

  • generating a multi-level, amplitude-modulated optical signal, the multi-levels modulated directly in the optical domain utilizing an optical modulator driven by first and second electrical input signals, wherein;

    said optical modulator configures more than two output levels in said multi-level amplitude modulated optical signal;

    drivers are coupled to said optical modulator; and

    said first and second electrical input signals are synchronized before being communicated to said drivers.
