Project Description

1064nm High Power Isolator & Band Pass Filter Hybrid Combination

The 1064nm High power Isolator &BPF is a combination of a BPF and a TGG based isolator in a single package. The BPF&isolator features low insertion loss, high isolation, high extinction ratio(PM) and high reliability and stability. The device guides optical light in one direction and block out unwanted noise signals, eliminates back reflection and back scattering in the reverse direction. The device can be built with bare fiber, or 900um jacket cable. The BPF Isolator is widely used in amplifier systems, fiber optic systems and fiber lasers.

If you do not see a standard BPF&isolator that meet your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed. DK Photonics can respond to custom requirements with short lead times.

  1. Above specification are for device without connector, and may change without notice.
  2. IL is 0.3 dB higher and RL is 5 dB lower, ER is 2dB lower (PM type) for each connector added.
  3. The pass optical power is 2 W only for connector added, the connector is only used for performance testing at low power, higher power requires splicing fibers.
  4. Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request (Only for PM type).
  5. If there is pulse application, please be sure to inform us of pulse energy and peak power.
  6. For high continuous power, we will add a port to export the blocked forward signal light to reduce the heat dissipation of the device. The user only needs to export it to the heat dissipation shell when using it.

Order information 

P/N: HP(PM)ISO&BPF-B/F-①-②-③-④-⑤-⑥-⑦-⑧(B: Both axis working , F:Fast axis blocked)

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail. For high power applications, we recommend direct splicing without connectors.
