| Popis: | We present a plasmonic modulator based on hybrid orthogonal silver junctions using vanadium dioxide as the modulating material on the silicon on insulator. The modulator has an ultra-compact footprint of 1.8{\mu}m x 1{\mu}m with a 100nm x 100nm modulating section based on the orthogonal geometry. We take advantage of large change in the refractive index of vanadium dioxide during its phase transition to achieve a high modulation depth of 46.89dB/{\mu}m. We also provide a fabrication strategy for the development of this device. The device geometry has potential applications in the development of next generation high frequency photonic modulators for optical communications which require a nanometer scale footprint, large modulation depth and small insertion losses.
