RGBV fiber optic components

Description

This dichroic RGBV Beam Combinersis a compact opto-mechanical units that combines four fiber-coupled sources with different wavelengths into a common output fiber cable with high efficiency.

Optical Setup
The four input ports are fiber-coupled to PM fiber cables.
The different wavelengths are superimposed by means of dichroic mirrors. A summery of typical splitters can be found here.
At the output port, a polarizer is placed in order to define the polarization at output of the system.

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