Flexible generation of an optical nonuniform bit-mapping signal based on an InP transmitter module is demonstrated. It can realize flexible bit mapping through the photonic modulation method, which can break the limitations of an electrical digital-to-analog convertor and field-programmable gate array. This module has potential to easily increase the signal rate or refine the granularity without electronics, which indicates it may be a future application to replace the traditional transmitter. The feasibility and performance of the proposed scheme are demonstrated in the experiment.
