Several leading manufacturers supply Fiber Bragg Gratings (FBGs), including Proximion, Advanced Optics Solutions GmbH, and Northlab Photonics AB.

Key Manufacturers

Proximion specializes in advanced FBG products, offering straight, chirped, and tilted gratings with customized group delay profiles. They use a proprietary writing technique that supports both small series and high-volume production, including ultra-long FBGs for wavelength-selective filtering and optical pulse shaping . Advanced Optics Solutions GmbH (AOS) provides FBGs for telecommunications and optical sensing applications. Their products function as filters, in-fiber cavities, wavelength references, and optical strain sensors, suitable for monitoring strain, pressure, or temperature . Northlab Photonics AB (Sweden) develops and supplies equipment for fiber processing and FBG manufacturing systems. They also produce high-reliability active and passive optical components for space, telecom, industrial, medical, and R&D applications .

Additional Suppliers

RP Photonics lists 43 suppliers of fiber Bragg gratings, including both manufacturers and distributors, offering a wide range of FBG types and configurations . Other directories, such as GoPhotonics, provide searchable lists of optical grating manufacturers, allowing selection based on location and capabilities .

Considerations When Choosing a Supplier

• Grating Type: Standard, chirped, or tilted FBGs depending on application needs.
• Customization: Some manufacturers offer tailored group delay profiles or ultra-long gratings.
• Volume and Automation: Evaluate whether the supplier can handle small-scale prototypes or large-scale production.
• Application Focus: Certain suppliers specialize in telecom, sensing, or research-grade components. These manufacturers and suppliers provide a broad spectrum of FBG solutions suitable for optical communications, sensing, and laser applications.
