Our recent publication in Optics Express introduces novel research on a thermo-optic VO2-based silicon waveguide mid-infrared router featuring asymmetric activation thresholds and large bi-stability. This study examines the routers’ performance, achieving power limiting levels of 56.5 dB in the forward operating mode and 64.5 dB in the reverse operating mode. Notably, the total transmission in the inactive mode reaches 75%. Furthermore, the study discusses the bi-stability and latching behavior exhibited by the router.
