We report on high-speed plasmonic-organic hybrid Mach-Zehnder modulators comprising ultra-compact phase shifters with lengths as small as 19 µm. Choosing an optimum phase shifter length of 29 µm, we demonstrate 40 Gbit/s on-off keying (OOK) modulation with direct detection and a BER < 6 × 10(-4). Furthermore, we report on a 29 µm long binary-phase shift keying (BPSK) modulator and show that it operates error-free (BER < 1 × 10(-10)) at data rates up to 40 Gbit/s and with an energy consumption of 70 fJ/bit.
我们报道了一种高速等离子体-有机混合马赫-曾德尔调制器，它包含长度小至19μm的超紧凑型移相器。选择29μm的最佳移相器长度，我们展示了采用直接检测的40 Gbit/s开关键控（OOK）调制，误码率（BER）<6×10⁻⁴。此外，我们报道了一种29μm长的二进制相移键控（BPSK）调制器，并表明它在高达40 Gbit/s的数据速率下无差错运行（BER<1×10⁻¹⁰），且能耗为70 fJ/bit。
