Our 1x2 and 2x2 high power micro optic tap couplers are used as fiber laser oscillator output couplers. They are also used in fiber laser and amplifier systems to monitor both forward laser intensity and backward ASE power. One of the two orthogonal polarization states is blocked with high extinction ratio to facility PM laser oscillation at a single polarization state. Its build-in high extinction ratio polarizers significantly improve laser performance. In fiber sensors, they are used for signal splitting and loop back detections.
The high power micro optic tap couplers offer very low excess loss and excellent environmental stability. Accurate and continuous coupling ratios from 50/50 to 1/99 are available with very good uniformity in a wide wavelength range. These components find extensive applications.
