Fiber optic based beam splitter

[Karthiksrao]

Hi,

Does any of you know any commercially available fiber optic - beam splitter?

It is very crucial for my experiment where I distribute an electromagnetic beam from one laser source (infrared) to two waveguides.. Since I am coupling using fibers, I require a fiber optic based beam splitter. . But I can't seem to find one that is available commercially.. Any suggestions?

Thanks,
Karthik

When you say infrared, what wavelength do you mean? Fibers are usually used to guide light around 1 micron, 1310 nm and 1550 nm (for other wavelengths you'd have difficulties finding fiber, let alone beam splitters).

Once you have a wavelength in mind, it is very straightforward to find beam splitters. Fiber beam splitters are also called couplers - they come in a variety of configurations (1x2, 2x2, 2x1, 1xN whatever) and split ratios (50/50, 90/10,...). There are also couplers for single mode fibers, multimode fibers, Polarization Maintaining fibers...

These are available all over the place, and are very cheap. I suppose it depends which part of the world you live in, just google for "single mode couplers" (or multimode, or whatever you want). You could try http://www.fiberinstrumentsales.com/ (I use them for my fiber needs, there are surely many others). Or you could get stuff from China, if you know companies you can trust. Can't beat the price!

Hello Karthik,

I am a scientist and I would be happy to help you with your question. Fiber optic based beam splitters are commonly used in scientific experiments and there are many commercially available options. Some popular brands include Thorlabs, Newport, and Edmund Optics. You can also find them on online marketplaces such as Amazon or eBay.

When looking for a fiber optic based beam splitter, there are a few factors to consider such as the wavelength of your laser, the splitting ratio (i.e. how much light is split between the two waveguides), and the type of fiber connector you need. Make sure to carefully read the specifications of the product to ensure it meets your experiment's requirements.

If you are having trouble finding a specific beam splitter, you can also consider using a fiber optic coupler and a polarization controller to achieve a similar effect. This would involve coupling the light from your laser into the coupler and using the polarization controller to split the light into two waveguides.

I hope this helps and good luck with your experiment! Let me know if you have any further questions.
