 a, Optical microscope image of a fabricated PT symmetry coupled dual-microresonators on AlGaAs-on-Insulator platform. b, Typical transmission spectrum of the PT symmetry structure supporting the high-speed signal operation. (c), Analytical (lines) and experimental (circles) conversion efficiency plotted as a function of the signal bandwidth at a pump power of 1 mW, showing two orders of magnitude boost of efficiency at 40 GHz signal bandwidth. (d), Bit-error rate (left) and eye diagram (right) of the converted idler (38 Gbit/s) at different pump power levels with a fixed signal power of 3.6 mW, showing error free operation, i.e., below hard-decision forward-error correction (HD-FEC) limit, at 1mW pump power.
