  Starlight corrupted by atmospheric turbulence cannot couple efficiently into
astronomical instruments based on integrated optics as they require light of
high spatial coherence to couple into their single-mode waveguides. Low-order
adaptive optics in combination with photonic lanterns offer a practical
approach to achieve efficient coupling into multiplexed astrophotonic devices.
We investigate, aided by simulations and an experimental testbed, the trade-off
between the degrees of freedom of the adaptive optics system and those of the
input waveguide of an integrated optic component leading to a cost-effective
hybrid system that achieves a signal-to-noise ratio higher than a standalone
device fed by a single-mode fiber.
