Based on mature fused-fiber technique, these polarization maintaining optical fiber couplers are fabricated to work at special short wavelengths, such as 633nm, 780nm, 850nm or 980nm. These wavelengths are of special interest with applications such as measurement, detection, sensors and fiber laser systems.


  • Low excess loss
  • High polarization extinction ratio
  • Customized coupling/tapping ratio
  • Compact package
  • High stability and reliability


  • Optical sensor systems
  • Optical fiber laser systems
  • Detection, measurement or optical signal processing


Ordering Information:
