The emerging technology of power-by-light enables power and data delivery over a single Free Space Optical (FSO) link for electrically isolated, interference-free remote operation. Telecom wavelength bands (λ ≈ 1550 nm) are well known for applications in data communication over optical fiber and overlap atmospheric transparency windows, extending the reach of FSO power and data systems through the air. This creates the opportunity to directionally deliver significant power (above 1mW) and high speed data wirelessly over long distances. FSO channels can experience turbulence and weather conditions that affect data and power transmission. Hence, they should be modeled and verified against measurements under varied atmospheric conditions. This will help improve model precision and robustness in predicting FSO channel performance. Accurate modeling of data transmission in FSO channels is urgently required to support the design of wireless optical communication systems for remote areas to which fiber deployment is difficult or uneconomic and instead long-range data communications between ground stations and High-Altitude Platform Systems (HAPS) may be employed. We have modelled an FSO channel transmitting data and power at 1550 and 1520 nm respectively under various meteorological conditions. The system model was developed in the commercially available OptiSystem software for modeling signals transmission. Different weather conditions translate directly to different FSO channel signal attenuations, impacting both data and power transmission. We also explore the impact of different modulation schemes such as Quadratic Amplitude Modulation (QAM), Pulse Amplitude Modulation (PAM), and Quadratic Phase Shift Keying (QPSK) on the bit error rate of the transmitted data thereby achieving the optimal required hardware design parameters. We found that QPSK is predicted to have the longest viable FSO range across all weather conditions and that power cannot be transmitted past 1 km in foggy weather.

Enabled by technological improvements, photonic devices and circuits are becoming increasingly more complex. Non-trivial geometries are designed to reduce device footprint, improve performance, and introduce novel functionalities. However, the number of design variables required to properly represent these geometries quickly grows, limiting the effectiveness of classical design approaches. Moreover, parameters are often strongly interdependent, restricting the use of sequential optimizations or independent parameter sweeps. Although several optimization techniques can be effective for multi-parameter design, they commonly allow to optimize for a single or a handful designs and the optimization process needs to be repeated if new performance criteria are introduced. In contrast to classical design approaches, the in uences of the design parameters remain hidden as well as the general behavior of the design space. In this paper we present an extension of our recent work on the application of machine learning pattern recognition to the design of multi-parameter photonic devices. In particular, we propose using a combination of local optimization based on the adjoint method and the use of dimensionality reduction. Adjoint optimization is used multiple times to generate a small set of different designs with high performance. Dimensionality reduction is applied to analyze the relationship between these degenerate designs and identify a lower-dimensional design sub-space that includes all alternative good designs. This sub-space can be mapped for any performance criteria thus enabling informed decisions based on the relative priorities of all relevant performance specifications. As a proof of concept, we demonstrate a ten-parameter design of an integrated photonic power splitter using silicon-on-insulator technology. We identify a region of possible high performance design solutions and select two design candidates either maximizing the splitter efficiency or minimizing back-reflection.
