Mode-strip assemblies for high optical beam quality without cladding modes to avoid thermal hotspots in the fibre cladding and transmit the highest power possible.
In mode-strip assemblies, undesired modes are diverted from the fibre cladding. This offers several advantages:
ModeStrip assemblies are specifically assembled according to customer requirements. Through precise controls in the outgoing goods area, we guarantee an eccentricity of <10 µm (and if desired, also <5 µm). We can equip the fibre end face with an AR coating on an optional basis. Upon request, we can also supply you with measurement reports on the attenuation and centricity values, as well as photos of the end faces.
In theory, the light in optical fibres is reflected several times without loss at the interface between the fibre core and the fibre cladding according to the principle of total reflection. In practice, however, small fractions of power can enter the fibre cladding. During the transmission of high power, as much as 2% to 3% can lead to the destruction of the fibre cable. Mode-strip connectors provide a remedy by stripping off the cladding modes and dissipating the resulting heat in a controlled manner via a cooling element. This prevents thermal destruction of the fibre connector and simultaneously improves the beam profile where the fibre exits.
