Extended Data Fig. 10: Data transmission performance.
a, Modulation bandwidth vs. data rate for the control, MA, PEA and t-BA devices. The data rates are defined at a bit error rate (BER) close to the 7% forward error correction threshold of 3.8 × 10−3. The data points of each colour are collected from 10 devices. Scatter plots are presented as mean values with error bars indicating the standard errors of the mean. Shaded areas indicate the 95% prediction interval for each linear fitting. b-d, Eye diagram demonstrations of a t-BA device (0.028 mm2) measured at the data rates of 20 Mbps (b), 50 Mbps (c) and 80 Mbps (d) with a 1.5 mA DC bias, corresponding to a BER of 1.5 × 10−5, 2.2 × 10−3 and 1.0 × 10−2, respectively. The t-BA device displays clear open eye diagrams up to 50 Mbps data rate and degrades when the baud rate increased to 80 Mbps.
