Where to Buy Fiber Bragg Gratings

DK Photonics offers fiber Bragg gratings for a wide range of applications in the areas of telecommunications, lasers and sensors. With excellent apodized technologies, we can offer high quality FBGs meeting different requirements of our customers.

FFA-01 is a fiber array sensor with configurable number of FBG elements and their spacing over the fiber length. FFA-01 is typically used for direct gluing to the measured surface to capture strain changes of the monitored structure.

Based on the Fiber Bragg Grating (FBG) technology and the newLight optical sensor series, the FS70 configurable arrays are optical fibers with multiple FBGs and high-performance coatings. These are optimally suited for multipoint measurement of strain in laboratories and in all kinds of industries.

In order for fiber Bragg gratings to function properly and for the optical signals to be reliable, it is essential that the FBGs are equipped with the connector types that are appropriate for the respective situation. When selecting the correct connector type, the mechanical stress and optical requirements must be taken into account.

Diamond can fall back on its extensive knowledge in the field of FBG sensor assemblies as well as in the development and manufacturing of sensor packaging, thus offering a wide range of ideal solutions for your requirements.

Premium quality fiber Bragg gratings and FBG arrays for customized sensors, polyimide-coated sensors to 300 °C, gold-coated hermetically sealed sensors, small-diameter FBGs, radiation hard/proof sensors, tilted FBGs, and high-temperature FBG sensors to 1000 °C. We also produce FBG matched pairs for fiber lasers and athermal FBG wavelength references.

Mastering advanced FBG writing technologies with holographic phase mask and e-beam phase mask, O/E Land can produce many different types of fiber Bragg gratings with different types of packaging. We have full license for the CRC/UTC Fiber Bragg Grating Technologies Portfolio, and have a vast inventory of fiber gratings.

O/E LAND INC. has also developed a strong expertise in the writing of multi-grating arrays with 2, 3, 4, 6 or up to 16 fiber gratings in a single fiber, with no need for splicing. Fiber Bragg grating arrays can be used in DWDM, CWDM optical systems to add or drop multiple channels simultaneously, and in sensors and for instrumentation purposes.

Exail (formerly iXblue) offers fiber Bragg gratings for a variety of applications: laser cavity mirrors, gain flattening filters, and ultra-narrow bandwidth filters. In conjunction with our extensive doped fiber portfolio, we can offer suitable fibers for single-frequency DFB lasers.
