Optical Injection Locking for Enhancing Communication Systems in Telesurgery: A Simulation-Based Study

The growing complexity of remote robotic surgery (RRS) has heightened the demand for communication systems that deliver ultralow latency, high bandwidth, and stable signal transmission. Conventional optical and wireless communication architectures often fail to satisfy these stringent requirements, particularly in time critical and high-fidelity data-exchange scenarios. In this study, a simulation-based evaluation of Optical Injection Locking (OIL) was conducted to investigate its potential in enhancing the signal quality and transmission efficiency for telesurgical applications. The results demonstrated that OIL significantly improves the frequency response characteristics, with the bandwidth reaching up to 32 GHz through controlled variation of the injection ratio. Furthermore, phase-noise suppression and spectral narrowing were observed with increasing wavelength detuning, contributing to improved signal coherence and reduced dispersion. The end-to-end latency was maintained below 50 ms, satisfying the safety constraints for real-time surgical interaction. The system also exhibited a 30% reduction in power consumption compared with conventional optical fiber systems. These findings confirmed the technical feasibility of OIL as a high-performance communication approach for latency-sensitive biomedical applications. Future work will focus on the prototype development and real-world integration of OIL-based links for next generation telesurgery platforms.
