We present the concept of simultaneous lightwave information and power transfer (SLIPT). Specifically, we propose novel and fundamental SLIPT strategies, which can be optimized and implemented in visible light or infrared communication systems, equipped with a simple solar panel at the receiver. These strategies are performed at the transmitter or at the receiver, or at both sides, and are named adjusting transmission, adjusting reception, and coordinated adjustment of transmission and reception. Furthermore, they affect the maximum value of harvested energy, information rate, and signal-to-noise plus interference ratio. Computer simulations reveal that the proposed strategies considerably increase the harvested energy, compared to SLIPT with fixed policies.
