Compact, rugged and highly efficient opto-mechanical unit with a dichroic wave plate and a polarization beam splitter
This fiber-coupled Beam Splitter1 ⇾2 is a compact opto-mechanical unit that split 2 fiber-coupled sources with different wavelengths into2 different output fiber cables with high efficiency.
Please note, that this configuration allows forsplitting two nearby wavelengths (wavelength difference < 10 nm).
In case of a larger difference in wavelength (> 10 nm) the configuration 48-MCS-011 is to be preferred.
Optical Setup
The input port is fiber-coupled to a PM fiber cable.
An input polarizer cleanes the linear state op polarization of the two input sources.
A dichroic wave plate rotates the linear state of polarization of one wafelength by 90° while the polarization of the second wavelength is not affected.
In an adjacent polarization beam splitter one wavelength is reflected whilse the other wavelength is transmitted.
In the deflected beam there is an polarizer that increases the polarization extinction ratio of the s-polarization.
Fiber Couplers
A fundamental component of a fiber-coupled Beam Splitter 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.
