Description

This Fiber Port Clusters2 ⇾ 2 dc Mod01 is a compact opto-mechanical unit that combines two fiber-coupled sources with differing wavelengths and then splits the combined radiation into 2 output fiber cables with high efficiency and variable splitting ratio. Electro-magnetic shutter is placed at each of the two input ports and output ports.

Optical Setup
The input port is fiber-coupled to a PM fiber cable. A polarizer defines the input polarization which is necessary for a long term stable splitting ratio.
A photo diode right after the input port allows for a continuous monitoring of the radiation.
Subsequently, the radiation splitting is achieved by using a rotary half-wave plate in combination with a polarization beam splitter. By use of the rotary half-wave plate, almost any desired splitting ratio can be achieved.
At the output ports further polarizers are placed in order to define the polarization at output of the system.

Fiber Couplers
A fundamental component of a Fiber Port Cluster is the Laser Beam Coupler, which is the input into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the polarization-maintaining fiber cables. The stability of the total Fiber Port Cluster is determined by the stability of the laser beam coupler.

Electro-magnetic Shutters
An electro-magnetic shutter is placed at each of the two input ports and output ports. For a description and further technical specifications, please refer to the electro-magnetic shutter type 48EMS-6.
