| Summary: | The metal-to-insulator transition (MIT) property of vanadium dioxide (VO<sub>2</sub>) has recently been used in several application fields such as plasmonics, sensing, metamaterials, and optical modulation. Due to the MIT nature, VO<sub>2</sub> allows a huge change in its complex refractive index that can be electrooptically controlled. In this paper, the analysis and design optimization of a 2 <inline-formula> <tex-math notation="LaTeX">$\times$</tex-math></inline-formula> 2 microring switch based on a hybrid VO<sub>2</sub>/silicon waveguide structure is addressed. Switching is achieved by exploiting the change in both absorption loss and phase shift that occurs in VO<sub>2</sub> when changing from the insulating to the metallic state. The device is optimized to minimize insertion losses and crosstalk. An active length of only 2.8 <inline-formula> <tex-math notation="LaTeX">$\mu\text{m}$</tex-math></inline-formula> is required to achieve a data throughput rate higher than 500 Gb/s at a single optical wavelength. |
