PM Fiber Array
The PM fiber array manufacture is based on placing fiber in the high precision V-Groove Chip with another flat V-Groove Lid on top of it. The end face of the fiber array is optically polished, and on request available also with antireflection coating (AR-Coating).DK Photonics Polarization Maintaining (PM) fiber arrays offer high polarization extinction ratio and excellent optical performance. We also provide customized designs for specific applications.
| Features | Applications |
| · High Polarization Extinction Ratio
· Excellent Optical Performance · Large Channel Count · Optional Fiber Metallization |
· PM photonic waveguide devices
· PM-collimator arrays · Multi-PM fiber collimators |
