In laser technology, optical output power often has to be coupled into optical fibres, and with as little loss as possible. Fibres with core diameters between from 200µm to 1500µm are commonly used to transmit laser power. We can assemble these fibres with either SMA or D80 connectors according to your custom requirements.
To avoid unwanted scatter from stray light, it is necessary to assemble ferrules with free-standing fibres by using a shorter ferrule. This allows any misdirected light that does not couple into the fibre to pass outside the ferrule and is effectively ‘beam dumped’ into the void surrounding the ferrule within the connector package.
One quality criterion in such assemblies is the centricity of the fibre core to the ferrule’s outer diameter. This plays a particularly important role in connectors without a keyway, like those used in polarisation maintaining (PM) fibres. In production, we achieve an excellent centricity of <10µm. This has a major advantage in field applications because assembled cables can be changed without any adjustment. To reduce the amount of reflections at the air/glass interface, we can also coat the fibre end faces if requested. The transmission of AR-coated fibres is improved by 3.5% to 4% per face.
