FiberLock – Automatic Single Mode Fiber Coupling

FiberLock – Automatic Single Mode Fiber Coupling

The FiberLock is an automatic single-mode fiber coupling unit (2D fiber scanner) consisting of the control electronics and an active mirror.

• fast scanning of the face of the fiber to help the initial setup
• 3D display of the coupling efficiency
• easy optimization due to the decoupling of degrees of freedom

• locking of the fiber coupling to maximum intensity
• search and re-lock functionalities

• locking of the intensity to a fixed value
