What SunCubes does

SunCubes Srl is a privately-held Italian deep-technology company founded in 2023 and headquartered in Milan that develops optical power transmission systems — technology that converts electrical energy into laser beams, transmits them through free space, and converts them back into regulated electricity at the receiver. The company's core technical stack spans four functional layers: optical power control (beam shaping, collimation, real-time closed-loop pointing/tracking with compensation for platform motion, vibration, and thermal drift); a wireless energy transmission link (line-of-sight optical beam replacing physical cables); wavelength-tuned photovoltaic receiver modules with engineered aperture geometry, power conditioning, and thermal management; and a safety architecture based on IEC 60825 laser safety frameworks with hardware interlocks independent of software, beam interruption detection, geofencing, and redundant sensing.

The company's flagship product is DEEP LIGHT, an underwater wireless power platform that uses blue-green laser beams (wavelength-optimized for water propagation) to deliver energy wirelessly to autonomous underwater vehicles (AUVs) and subsea systems over distances of several tens of meters. DEEP LIGHT has been awarded and is supported by the Italian Navy through the Polo Nazionale della Dimensione Subacquea (PNS) as a strategic initiative for national underwater technological capabilities. The broader Optical Power Transmission System product family is positioned for defense, research, and commercial maritime applications where cables, batteries, and solar panels fail operationally.

SunCubes generates revenue through hardware sales of integrated transmission systems and licensing/integration of its beam-control technology to defense partners. The company's go-to-market operates via strategic OEM embedding partnerships — most notably the June 2026 'Laser Arm' alliance with NUBURU and Lyocon, which combines Lyocon's laser-source manufacturing with SunCubes' beam-control and optical power-beaming capabilities for counter-drone, directed-energy, and critical-infrastructure defense applications across U.S. and European markets. SunCubes also received up to €1 million in strategic investment from NUBURU structured as advance payments toward a future capital increase, subject to Golden Power clearance and export-control approvals. Earlier, the company raised approximately $1.29 million in a July 2025 round led by RoboIT with participation from CrossConnect, ELIS, and Plug and Play.

Core offering

SunCubes develops optical power transmission systems that convert electrical energy into laser beams and convert them back to regulated electricity at the receiver, replacing physical cables for both terrestrial and underwater applications. The company's DEEP LIGHT platform uses blue-green laser beams to wirelessly power autonomous underwater vehicles and subsea systems for defense, research, and commercial maritime customers. Core offerings include complete transmitter and receiver modules with proprietary beam-control, real-time tracking, and IEC 60825-compliant safety architecture.

Product overview

SunCubes offers an optical wireless power transmission system comprising transmitter modules and receiver modules that work together as a complete beam-control and power-beaming solution. Their DEEP LIGHT platform specifically targets underwater applications, using blue-green laser beams to power autonomous underwater vehicles. The transmitter module handles beam shaping, alignment, tracking, and safety monitoring, while the receiver module captures the optical beam and converts it to regulated electrical power. The system is designed for applications where cables, batteries, and solar panels fail operationally.
