You are likely at least slightly aware of the work that famed engineer, scientist, and researcher Nikola Tesla did in the early 1900s in his futile attempt to wirelessly transmit usable power via a 200-foot tower. The project is described extensively on many credible web sites, such as “What became of Nikola Tesla’s wireless dream?” and “Tesla’s Tower at Wardenclyffe” as well as many substantive books.

Since Tesla, there have been numerous other efforts to transmit power without wires using RF (microwave and millimeter waves) and optical wavelengths. Of course, both “bands” are wireless and governed by Maxwell’s equations, but there are very different practical implications.

Proponents of wireless transmitted power see it as a power-delivery source for both stationary and moving targets including drones and larger aircraft—very ambitious objectives, for sure. We are not talking about near-field charging for devices such as smartphones, nor the “trick” of wireless lighting of a fluorescent bulb that is positioned a few feet away from a desktop Tesla coil. We are talking about substantial distances and power.

Most early efforts to beam power were confined to microwave frequencies due to available technologies. However, they require relatively larger antennas to focus the transmitted beam, so millimeter waves or optical links are likely to work better.

The latest efforts and progress have been in the optical spectrum. These systems use a fiber-optic-based laser for a tightly confined beam. The “receivers” for optical power transmission are specialized photovoltaic cells optimized to convert a very narrow wavelength of light into electric power with very high efficiency. The reported efficiencies can exceed 70%, more than double that of a typical broader-spectrum solar cell.

In one design from Powerlight Technologies, the beam is contained within a virtual enclosure that senses an object impinging on it—such as a person, bird, or even airborne debris—and triggers the equipment to cut power to the main beam before any damage is done (Figure 1). The system monitors the volume the beam occupies, along with its immediate surroundings, allowing the power link to automatically reestablish itself when the path is once again clear.

Although this is nominally listed as a “power” project, as with any power-related technology, there’s a significant amount of analog-focused circuitry and components involved. These provide raw DC power to the laser driver and to the optical-conversion circuits, lasers, overall system management at both ends, and more.

Recent progress raises effectiveness

In May 2025, DARPA’s Persistent Optical Wireless Energy Relay (POWER) program achieved several new records for transmitting power over distance in a series of tests in New Mexico. The team’s POWER Receiver Array Demo (PRAD) recorded more than 800 watts of power delivered during a 30-second transmission from a laser 8.6 kilometers (5.3 miles) away. Over the course of the test campaign, more than a megajoule of energy was transferred.

In the never-ending power-versus-distance challenge, the previous greatest reported distance records for an appreciable amount of optical power (>1 microwatt) were 230 watts of average power at 1.7 kilometers for 25 seconds and a lesser (but undisclosed) amount of power at 3.7 kilometers (Figure 2).

To achieve the power and distance record, the power receiver array used a new receiver technology designed by Teravec Technologies with a compact aperture for the laser beam to shine. That’s to ensure that very little light escapes once it has entered the receiver. Inside the receiver, the laser strikes a parabolic mirror that reflects the beam onto dozens of photovoltaic cells to convert the energy back to usable power (Figure 3).

Figure 3 In the optical power-beaming receiver designed for PRAD, the laser enters the center aperture, strikes a parabolic mirror, and reflects onto dozens of photovoltaic cells (left) arranged around the inside of the device to convert the energy back to usable power (right).

While it may seem logical to use a mirror or lens when it comes to redirecting laser beams, the project team instead found that diffractive optics were a better choice because they are good at efficiently handling monochromatic wavelengths of light. They used additive manufacturing to create optics and included an integrated cooling system.

Further details on this project are hard to come by, but that’s almost beside the point. The key message is that there has been significant progress. As is usually the case, some of it leverages progress in other disciplines, and much of it is “home made.” Nonetheless, there are significant technical costs, efficiency burdens, and limitations due to atmospheric density—especially at lower attitudes and ground level.

Do you think advances in various wireless-transmission components and technologies will reach to where it’s a viable power-delivery approach for broader uses besides highly specialized ones? Can it be made to work for moving targets as well as stationary ones? Or will this be one of those technologies where success is always “just around the corner”? And finally, is there any relationship between this project and the work on directed laser energy systems to “shoot” drones out of the sky, which has parallels to the beam generation/emission part?

Broadcom Inc. launches the Tomahawk 6 – Davisson (TH6-Davisson), the company’s third-generation co-packaged optics (CPO) Ethernet switch, delivering the bandwidth, efficiency, and reliability for next-generation AI networks. The TH6-Davisson provides advances in power efficiency and traffic stability for higher optical interconnect performance required to scale-up and scale-out AI clusters.          

The trend toward CPOs in data centers is to increase bandwidth and lower energy consumption. With the TH6-Davisson, Broadcom claims the industry’s first 102.4 Tbits/s of optically enabled switching capacity, doubling the bandwidth of any CPO switch available today. This sets a new benchmark for data-center performance, Broadcom said.

(Source: Broadcom)

Designed for power efficiency, the TH6-Davisson heterogeneously integrates TSMC Compact Universal Photonic Engine (TSMC COUPE) technology-based optical engines with advanced substrate-level multi-chip packaging. This is reported to dramatically reduce the need for signal conditioning and minimize trace loss and reflections, resulting in a 70% reduction in optical interconnect power consumption. This is more than 3.5× lower than traditional pluggable optics, delivering a significant improvement in energy efficiency for hyperscale and AI data centers, Broadcom said.

In addition to power efficiency, the TH6-Davisson Ethernet switch addresses link stability, which has become a critical bottleneck as AI training jobs scale, the company added, with even minor interruptions causing losses in XPU and GPU utilization.

The TH6-Davisson solves this challenge by directly integrating optical engines onto a common package with the Ethernet switch. The integration eliminates many of the sources of manufacturing and test variability inherent in pluggable transceivers, resulting in significantly improved link flap performance and higher cluster reliability, according to Broadcom.

In addition, operating at 200 Gbits/s per channel, TH6-Davisson doubles the line rate and overall bandwidth of Broadcom’s second-generation TH5-Bailly CPO solution. It seamlessly interconnects with DR-based transceivers as well as NPO and CPO optical interconnects running at 200 Gbits/s per channel, enabling connectivity with advanced NICs, XPUs, and fabric switches.

The TH6-Davisson BCM78919 supports a scale-up cluster size of 512 XPUs and up to 100,000+ XPUs in two-tier networks at 200 Gbits/s per link. Other features include 16 × 6.4 Tbits/s Davisson DR optical engines and field-replaceable ELSFP laser modules.

Broadcom is now developing its fourth-generation CPO solution. The new platform will double per-channel bandwidth to 400 Gbits/s and deliver higher levels of energy efficiency.

The TH6-Davisson BCM78919 is IEEE 802.3 compliant and interoperable with existing 400G and 800G standards. Broadcom is currently sampling the Ethernet switch to its early access customers and partners.
