Compact, rugged and highly efficient opto-mechanical unit with Polarization beam splitter and a dichroic wave plate
This fiber-coupled Beam Combiner 2 ⇾ 1 is a compact opto-mechanical unit that combines 2 fiber-coupled sources with different wavelengths into 1 output fiber cable with high efficiency.
Please note, that this configuration allows for superimposing two nearby wavelengths (wavelength difference < 10 nm).
In case of a larger difference in wavelength (> 10 nm) the configuration 48-MCS-016 is to be preferred.
Optical Setup
The input ports are each fiber-coupled to PM fiber cables.
The radiation is superimposed by means of a polarization beam splitter
An adjacent dichroic wave plate rotates the linear state of polarization of one wavelength by 90° while the polarization of the second wavelength is not affected.
A common polarizer cleans the linear state of polarization of the superimosed sources.
Fiber Couplers
A fundamental component of a fiber-coupled Beam Combiner are the Laser Beam Couplers, which are the inputs into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the common polarization-maintaining fiber cable. The stability of the total Beam Splitter is determined by the stability of the laser beam coupler.
