Caption

(a) Experimental set-up of the photonic transmission system carrying single-subchannel 2.5-GHz broadband 16-QAM signals. (b) Relationship between the transmission data rate and the BER achieved in the chip. The insets of (b) show the constellations of transmitted 16-QAM signals below the HD-FEC threshold marked by red and blue stars.
