  In ground-based astronomy, starlight distorted by the atmosphere couples
poorly into single-mode waveguides but a correction by adaptive optics, even if
only partial, can boost coupling into the few-mode regime allowing the use of
photonic lanterns to convert into multiple single-mode beams. Corrected
wavefronts result in focal patterns that couple mostly with the circularly
symmetric waveguide modes. A mode-selective photonic lantern is hence proposed
to convert the multimode light into a subset of the single-mode waveguides of
the standard photonic lantern, thereby reducing the required number of outputs.
We ran simulations to show that only two out of the six waveguides of a 1x6
photonic lantern carry >95% of the coupled light to the outputs at $D/r_0 < 10$
if the wavefront is partially corrected and the photonic lantern is made
mode-selective.
