“…This is a major step towards validating as-grown nanostructures as an approach to not only small and exotic but also high-performance photonics. optical power transfer 40 . In particular, we argue that nanostructure-based PV devices are far better suited as optoelectronic power supplies than solar cells.…”

Harnessing light with photonic circuits promises to catalyse powerful new technologies much like electronic circuits have in the past. Analogous to Moore's law, complexity and functionality of photonic integrated circuits depend on device size and performance scale. Semiconductor nanostructures offer an attractive approach to miniaturize photonics. However, shrinking photonics has come at great cost to performance, and assembling such devices into functional photonic circuits has remained an unfulfilled feat. Here we demonstrate an on-chip optical link constructed from InGaAs nanoresonators grown directly on a silicon substrate. Using nanoresonators, we show a complete toolkit of circuit elements including light emitters, photodetectors and a photovoltaic power supply. Devices operate with gigahertz bandwidths while consuming subpicojoule energy per bit, vastly eclipsing performance of prior nanostructure-based optoelectronics. Additionally, electrically driven stimulated emission from an as-grown nanostructure is presented for the first time. These results reveal a roadmap towards future ultradense nanophotonic integrated circuits.

“…Because of these advantages, OPD technology has already been applied to high-voltage applications and in other hazardous or electromagnetically noisy environments [1]. Other applications to sensing networks and power-over-optical local-area-network systems have already been proposed [2][3][4]. Light sources with high output power, efficient transmission media, and photovoltaic power converters are the key components for OPD applications.…”

We investigated the optical power delivery (OPD) limit of standard single-mode fibers (SMFs) at a wavelength of 1550 nm. We demonstrate that the intrinsic limits on OPD of SMFs are the fiber transmission loss and the nonlinear effect of stimulated Raman scattering (SRS). These limits cannot be overcome without choosing a different operation wavelength. We employed a C-band amplified spontaneous emission source pumped by a highpower erbium-doped fiber-optical amplifier as a broadband light source. As a result, the nonlinear effect caused by stimulated Brillouin scattering was successfully suppressed. By using this technique, we succeeded in delivering 3.5 W of optical power over a 5-km-long SMF. In addition, we demonstrated that the SRS becomes the main power-limiting factor when the delivery distance exceeds 5 km. We also used commercially available photovoltaic cells to convert optical power into electric power, and we confirmed a conversion efficiency of 17.4%. Consequently, about 500 mW of electric power can be delivered by using a 5-km-long SMF. We can construct an OPD system that can deliver electric power of the order of several hundreds of milliwatts over a distance of more than 5 km through SMF. Our results will be useful with a view to realizing long-range OPD systems such as an application of sensing network.
