光无线电力传输（OWPT）具有许多优点。为了提高光波导的效率，我们通过串联垂直腔面发射激光器（VCSEL）阵列芯片来降低电流，以减少电缆损耗。所制备的具有850 nm波长和20 W光输出功率的高输出功率串联连接的VCSEL阵列模块显示出增加的光源效率。通过使用串联连接的模块，GaAs太阳能电池的输出电功率为7.5W，功率传输效率为15%。传输到2.3米的距离被证明没有效率恶化。所获得的结果可以应用于混合式直流断路器的控制器的电源，这需要高的电绝缘。它也是有用的基础知识，适用于各种OWPT系统的建设。
Optical wireless power transmission (OWPT) has numerous advantages. To improve the efficiency of the OWPT, we decreased current by series connection of vertical cavity surface emitting laser (VCSEL) array chips to reduce cable loss. The fabricated high-output-power series-connected VCSEL array module with a wavelength of 850 nm and 20 W light output power showed increased light source efficiency. By using the series-connected module, an output electrical power of 7.5 W from the GaAs solar cell and a power transmission efficiency of 15% were achieved. Transmission up to a distance of 2.3 m was demonstrated without efficiency deterioration. The obtained results can be applied to the power supply to a controller of a hybrid DC circuit breaker, which requires high electrical insulation. It is also useful as a fundamental knowledge applicable to the construction of various OWPT systems.
