Search for gravitationally lensed interstellar transmissions

We consider interstellar light transmission aided by a gravitational lens. We find that optimal reception efficiency occurs in lensing geometries where the transmitter, lens, and receiver are nearly aligned. We explore various signal detection strategies, employing both existing and emerging technologies. With this study, our understanding of interstellar power transmission via gravitational lensing has significantly progressed. We observe that detection signals from nearby stars, may leverage established photonics and optical engineering technologies, and networks of collaborative astronomical facilities. Our findings confirm the feasibility of interstellar power transmission via gravitational lensing, directly impacting ongoing optical SETI efforts.
