摘要

本文首次实验证明了一种基于硅光子晶体(PhC)波导的超紧凑硅电光调制器。通过将载流子注入到马赫-曾德尔干涉仪(MZI)结构的80mm长的硅PhC波导中，演示了调制操作。在1567 nm处的调制深度为92%。通过有源区域的相移驱动电流Ipi低至0.15 mA，相当于采用50Omega阻抗匹配结构时的Vpi为7.5 mV

80-micron Interaction Length Silicon Nano-Photonic Crystal Waveguide Modulator

An ultra-compact silicon electro-optic modulator is experimentally demonstrated based on silicon photonic crystal (PhC) waveguides for the first time to our knowledge. Modulation operation was demonstrated by carrier injection into an 80mum-long silicon PhC waveguide of a Mach-Zehnder interferometer (MZI) structure. The modulation depth operating at 1567 nm is 92%. The pi phase shift driving current, Ipi, across the active region is as low as 0.15 mA, which is equivalent to a Vpi of 7.5 mV when a 50Omega impedance-mate structure is applied
