对更快、更高效的计算和通信设备的需求激发了人们对全光调制器领域的兴趣。本文提出了一种利用亚波长Au/VO 2纳米结构的小尺寸等离子体-光子混合全光波导调制器作为高调制光驱动调制器。使用时域有限差分模拟，纳米级（320 nm × 300 nm横截面）优化调制器的设计。该调制器的消光比高达26.85dB/μ m，长度仅为550 nm。
The need for ever faster and more efficient computation and communication devices has spurred interest in the field of all-optical modulators. Here a small-size hybrid plasmonic-photonic all-optical waveguide modulator utilizing a subwavelength Au/VO2 nanostructure is proposed as a high-modulation optically actuatable modulator. Using finite-difference-time-domain simulations, a nanoscale (320 nm x 300 nm cross-section) optimized modulator is designed. The modulator design has an extinction ratio as high as 26.85 dB/mu m, and a length of only 550 nm.
