Microknot resonators (MKRs), locally fused using a two-probe technique, have exhibited significantly improved optical performance and mechanical stability. They have been operated with low losses both in situ and as transferred devices. We found consistently more than threefold dynamical range enhancement, which remained stable in time, in electrically fused MKRs. These devices can be harbored in next-generation optical sensors, actuators, and optomechanical applications incorporating MKR-assisted microstructures taking advantage of this simple and robust fusing technique.
