Dynamic control of higher-order modes in hollow-core photonic crystal fibers

We present a versatile method for selective mode coupling into higher-order modes of photonic
crystal fibers, using holograms electronically generated by a spatial light modulator. The method
enables non-mechanical and completely repeatable changes in the coupling conditions.
