Doped Fiber Combiner, MPSC(N+1)x1

Doped fiber combiner combines 1 or 2 pump power source into a doped fiber directly. The splicing point is behind the coupling region, which has two advantages over standard combiner:

1) Customer only needs splice one time with doped fiber at combiner signal side.
2) The coupling region is behind splicing point, the isolation (backward signal to pump) is much lower than normal passive combiner to protect pump LD.

Polarisation coupler

Polarisation insensitve PM coupler (PIPMC 1×2 or 2×2)

The PIMPMC can work at designed coupling ratio at both fast and slow axis.

Polarisation maintaining coupler (1×2 or 2×2)

PMC is built with FBT technique with PM fiber and is widely used for optical sensors and optical gyro, etc.
Its coupling efficiency can be easily adjusted upon customer’s request.
