Abstract: A directly modulated multi-level optical signal generator and a method thereof are provided. The multi-level optical signal generator includes N number of direct modulation lasers (DMLs) configured to directly modulate source light into a 2-level optical signal, and an optical power combiner configured to combine N number of 2-level optical signals directly modulated by the respective DMLs to generate a 2N-level optical signal.
