Laser wireless energy information synchronization transmission technology can transmit signals while transmitting energy, reducing the system's reliance on communication devices. It effectively reduces system weight while increasing energy utilization, making it valuable for long-distance wireless energy transfer systems with low signal rate requirements. In this paper, a finite element simulation model for laser power converter is established. Using this model, the impact of signal energy intensity and load resistance on signal transmission under low-speed signal transmission conditions is studied. The research indicate that under the same signal energy conditions, the signal intensity increases and then decreases with the increase in load resistance, and the optimal signal load resistance occurs earlier than the optimal power transmission load resistance. Additionally, as the signal energy increases, the difference between the signal load resistance and the power transmission load resistance also increases. The mismatch between the maximum signal load resistance and the optimal power transmission load resistance inevitably involves a trade-off between energy and signal. Based on this, the paper discusses the selection method of load resistance in the energy-carrying communication process and calculates the loss of signal intensity and transmission energy under different load resistances. The conclusions of this research provide reference for the field of laser energy-carrying communication.
