G&H’s 50W Amplifiers are Key to Groundbreaking Research in Free-Space Optical Communications
G&H, a leader in space photonics, takes immense pride announcing the groundbreaking research published in Optics Letters. This pioneering work, a collaborative effort between G&H, Thales Research and Technology Palaiseau, and Thales Alenia Space Toulouse, introduces “Optical Coherent Combination of High-Power Optical Amplifiers for Free-Space Optical Communications.” Free Space Optical Communications Feeder Free Space Optical Communication (FSOC) links serve as high-capacity channels for transmitting data within a network of space assets, often involving geostationary satellites positioned at significant distances from Earth. FSOC holds great potential for the future of satellite communication. Given the exceptional data rates and vast distances between satellites, robust amplification of telecom signals is crucial. High power amplification is necessary due to the remarkably low probability to signal carrying photons successfully reaching their intended destination – the huge distances meaning as little as 1 in 100,000,000 sent photons are received. FSOC links: - Utilize laser light to transmit significantly more data than conventional radio frequencies allow - Benefit from wide optical bands - Are exempt from frequency regulation - Seamlessly integrate with terrestrial networks FSO links offer a promising solution for transmitting data between satellites and optical ground stations (OGS). The Challenge: Optical Feeder Uplinks A significant challenge arises when it comes to the optical feeder uplink – generating powerful enough optical carriers to transmit communication signals from OGS to geostationary satellites. Achieving high data rates, exceeding terabits per second, requires increasing the optical output power at OGS beyond currently available levels. This study enables multi-gigabits per second data transfer at power levels within the 100W range in the C-band, with minimal performance penalties related to the generation of the very high powers utilized. The research employs two of G&H’s 50W C-band amplifiers, highlighting the potential of G&H’s technology for the next generation of high-power, high-throughput ground-to-space feeder FSOC links. The research team used two methods to achieve very high optically powers. First, by directly leveraging G&H’s leading very high-power amplifier technology, and second, by harmonizing the outputs of two amplifiers through a process termed coherent combination. Coherent combination is where multiple sources/amplifiers are utilized in a manner that is akin to using a single source/amplifier, such that little beam quality degradation occurs. This is achieved via locking the relative phase of the sources/amplifier over time. Summary The paper demonstrates two world firsts - the highest power transmitted directly from an amplifier at a telecoms wavelength, whilst preserving a high data rate telecoms signal (25 Gb/s at 50W). Secondly the highest power output from a coherently combined source at telecom wavelengths whilst maintaining a high-speed telecom signal (25 Gb/s at 80W). The work introduces a state-of-the-art coherent beam combining (CBC) system with potential applications in long-range free space optical (FSO) communications, specifically ground-to-space feeder links. Matthew Welch, Chief Engineer of Fiber Optic Systems for G&H stated, “Being part of this project has been truly rewarding. We have demonstrated that G&H’s amplifier technology is future ready, and that G&H is paving the way for transformative applications in long-range free space optical communications, including vital ground-to-space feeder links.” The publication in Optics Letters reflects the significance of this research, within the photonics community. G&H commends the entire team involved for their remarkable contributions, as their work opens new avenues for high-throughput ground-to-satellite optical feeder link applications.

The Advantages of SWIR for Daytime Detection in C-UAS
In the rapidly evolving field of counter-Unmanned Aircraft Systems (C-UAS), the choice of optics plays a crucial role in ensuring effective detection and response. Shortwave imaging systems offer several advantages over visible and midwave imaging systems for daytime range detection, making them a critical inclusion in any multi-sensor C-UAS payload. In this discussion, we will explore why shortwave zoom lenses are exceptionally well-suited for countering the emerging threats posed by unmanned aerial systems and why G&H StingRay's FireAnt series is uniquely positioned to address that need in particular. General Advantages of SWIR for Daytime Range Detection and Tracking: Atmospheric Transparency: Shortwave infrared (SWIR) light experiences less atmospheric absorption and scattering compared to both visible and midwave infrared (MWIR) light during the day. This means that SWIR imaging systems can see through atmospheric disturbances, such as haze, dust, and fog, more effectively. This improved visibility is crucial for long-range detection during daylight hours. Solar Glint and Background Radiation: SWIR sensors are less susceptible to solar glint, the reflection of sunlight off objects, compared to MWIR sensors. MWIR sensors can be overwhelmed by the bright background radiation from the sun, which can limit their effectiveness during the daytime. SWIR sensors, on the other hand, can operate more effectively in the presence of strong sunlight, allowing for better range detection. Reduced Heat Signature: Unlike MWIR systems, SWIR imaging systems do not detect thermal radiation. This means that they are less affected by variations in temperature and do not suffer from the same challenges as MWIR systems when it comes to distinguishing between objects with similar thermal profiles. In daytime conditions, this can lead to improved accuracy in range detection. Improved Target Discrimination: SWIR imaging systems often provide better target discrimination and identification due to their ability to detect variations in material properties. This can be especially important during daytime operations when identifying specific objects or targets is critical. That's a pretty compelling argument for the incorporation of SWIR in C-UAS generally, but not all SWIR imaging systems are created equal and G&H StingRay has long been the industry's leader in this space. That's why we confidently announce the newest addition to the FireAnt series, our ruggedized F/6 80-800mm zoom lens. Designed for direct compatibility with 5µm and 10µm SXGA image formats, the 80-800mm FireAnt is a testament to a performance-first design methodology that incorporates SWIR specific materials and anti-reflection coatings, an approach yielding the best resolution and transmission available in a COTS SWIR imaging system. Many commercially available visible and shortwave zooms allow for a reduction in aperture as you move from the wide field to narrow field positions, whereas every FireAnt lens offers a constant aperture through its respective zoom range, a feature that lends itself directly to C-UAS applications: Advantages of a Constant Aperture for C-UAS: Target acquisition and tracking: It's crucial to quickly acquire and track threats. A zoom lens with a constant aperture allows for seamless zooming without changes in exposure, which aids in maintaining a clear and consistent view of the target. This is particularly important in dynamic situations where rapid adjustments are necessary. Depth of field control: The ability to control depth of field can help isolate and focus on specific subjects or areas of interest, enhance object recognition, or aid in target identification. A constant aperture zoom lens allows for consistent depth of field control throughout the zoom range, ensuring clear and sharp focus regardless of the focal length used. Consistent power density: A constant aperture zoom lens helps maintain a consistent power density when imaging a laser beam throughout the zoom range. This is important for shortwave targeting applications where maintaining a specific power density is crucial for effective operation. Consistency in power density ensures consistent performance and reliable results across different zoom levels. G&H | StingRay - Industry Leading High-Performance SWIR: In conclusion, as the field of counter-Unmanned Aircraft Systems (C-UAS) continues to evolve, the choice of optics becomes paramount for effective detection and response. Shortwave imaging systems, particularly SWIR zoom lenses, offer distinct advantages over visible and midwave systems, especially during daytime range detection. They excel in atmospheric transparency, are less susceptible to solar glint and background radiation, exhibit a reduced heat signature, and provide superior target discrimination. Among SWIR zoom lenses, G&H StingRay's FireAnt series stands out as an industry leader. The latest addition, the ruggedized F/6 80-800mm zoom lens, is designed for optimal performance, incorporating SWIR-specific materials and anti-reflection coatings. Its constant aperture feature enhances target acquisition, depth of field control, and power density consistency, making it an ideal choice for C-UAS applications. G&H StingRay's commitment to innovation continues to address the evolving challenges posed by unmanned aerial systems, ensuring reliable and effective solutions in the fight against emerging threats.
