Star product: We have multimode pump/signal combiners for high power applications with exceptional characteristics!.
|cladding mode strippers||S E|
Our cladding power strippers are used in high-power fiber lasers and amplifiers which need to handle substantial optical powers. The devices ensure that these powers are absorbed in a sufficiently widespread region, and that the generated heat can be removed safely, without damaging the mode stripper or any surrounding parts. We can provide them with all kinds of double-clad fiber and for cladding powers up to 500 W.
|coherent beam combining components||S E|
Our polarization beam combiners/splitters can be used either as polarization beam combiners to combine light beams from two PM input fibers into a single output fiber, or as a polarization beam splitters for splitting light from an input fiber into two output fibers with orthogonal polarization states. The most common application is to combine the light of two pump lasers into one single fiber in order to double the pump power for a EDFA or Raman amplifier.
|Faraday circulators||S E|
DK Photonics offers polarization-maintaining fiber-optic circulators for a wide range of wavelengths between 532 nm and 2050 nm.
|Faraday isolators||S E|
Our polarization-maintaining Faraday isolator features low insertion loss, high isolation, high extinction ratio and high reliability and stability. The device is available with bare fiber or with a 900-μm jacket cable.
|Faraday rotator mirrors||S E|
DK Photonics offers polarization-maintaining Faraday mirrors for use in fiber-optic networks and measurement applications. It can help to eliminate the polarization sensitivity of optical fiber systems.
|Faraday rotators||S E|
Our in-line Faraday rotator is characterized by low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability. It is available with fiber input and output. It is ideal for polarization-maintaining fiber amplifiers, fiber lasers, and high-speed communication systems and instrumentation applications.
|fiber amplifiers||S E|
DK Photonics offers various erbium-doped fiber amplifiers for telecom applications, including compact amplifier modules as well as bench-top instruments with controls and displays.
Ytterbium-doped amplifiers for the 1-μm wavelength region are also available.
|fiber Bragg gratings||S E|
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.
|fiber cables||S E|
DK Photonics offers polarization-maintaining (PM) optical patch cords for use in polarization-sensitive fiber optical systems. They are available with various types of fiber connectors.
|fiber collimators||S E|
Our polarization-maintaining fiber collimator has a high extinction ratio, low insertion and high return loss. The unique processing and high-quality AR coating also enable this collimator to handle high optical powers.
|fiber couplers||S E|
DK Photonics uses a unique fusing technique and polarization-maintaining fibers to fabricate the polarization maintaining fused coupler (PMC). The coupling ratio can be selected according to the customer’s request. It features low excess loss, small size and high polarization extinction ratio. PMC is widely used for optical sensors and optical gyros.
|fiber lasers||S E|
DK Photonics offers various kinds of fiber lasers:
|fiber mode field adapters||S E|
Our mode fields adapters allow one to combine fibers with different core diameters and NA with reduced splicing loss, usually <0.5 dB or even <0.3 dB.
|fiber-optic attenuators||S E|
Our polarization-maintaining mechanical variable optical attenuator is a useful tool for tests of optical components and systems. All input and output fibers are polarization maintaining, and devices for a wide range of wavelengths are available. The devices feature a low minimum insertion loss, high extinction ratio, high return loss and high adjustment precision.
Our in-line polarizer can be used to separate polarization components or to further enhance the polarization extinction ratio of signals. It is ideal for high-speed communication systems and test instrumentation where a high polarization extinction ratio is required.
|fiber-optic pump combiners||S E|
DK Photonics offers pump combiners built by engineers with solid knowledge and technical background. The devices offer high quality and low cost. We also offer great service.
Our fiber polarization controllers come preloaded with fiber. The fibers in the preloaded controllers can also be removed and replaced by the user if the controllers are needed for a new application in the future.
|superluminescent sources||S E|
DK Photonics offers fiber-based broadband ASE sources emitting in the telecom wavelength bands C and/or L or around 1060 nm.
|wavelength division multiplexing devices||S E|
DK Photonics offers filter WDM couplers based on advanced micro-optic filter technology. All input and output fibers are polarization-maintaining. They feature wide-band operation, low insertion loss, high polarization extinction, high return loss and a compact package. They are ideal for PM fiber amplifiers, fiber lasers and instrumentation applications.
|wavelength-tunable light sources||S E|
Our tunable fiber laser covers the C-band and can address up to 89 different ITU-T standard wavelengths (with 50 GHz separation). It contains a dual Fabry–Pérot cavity tuning etalon and a high gain chip, featuring high output optical power, narrow linewidth and high wavelength accuracy. It is equipped with a dedicated drive control circuit, high-definition color LCD screen, and optional control keyboard and PC software.
