Beam Splitters and Combiners
Frequently Asked Questions
Some fiber beam splitters contain a classical glass cube beam splitter. Light arriving at the surface diagonal of the cube will meet a special coating that would transmit some of it and reflect the rest. The amount of light transmitted or reflected depends on the coating transmission and reflection coefficients. Once split, these beams are coupled into optical fibers. Other designs of fiber beam splitters take advantage of evanescent coupling to split the input beam into two arms or outputs. Light coming from one arm will oscillate back and forth between two channels over their overlap region and then split into two separate outputs.
Depending on the design and the application, beam splitters and combiners can be made of cube beam splitters, lenses, half-mirrors, fibers, and waveguides.
Yes, many manufacturers offer customizable beam splitter ratios.
Fiber beam splitters play a crucial role in optical communication systems, but they are especially to important in quantum information applications such as quantum computing. They can be used to encode information, build interferometers, and preform multiplexing.
Some beam splitters are polarization-maintaining, others are not.
It depends on the polarization properties of the beam splitters. In polarization-maintaining beam combiners or splitters, single-mode fibers are used as it is only possible to maintain polarization using this type of fiber of few-mode fibers. Beam splitters that are not polarization-maintaining are typically made using multimode fibers.
While 2-port and 3-port combiners are very popular choices, beam combiners are not limited to combining 2 beams only. Some beam combiner designers can interfere up to 8 input beams in order to produce one output.
