  One key advantage of single-mode photonic technologies for interferometric
use is their ability to easily scale to an ever increasing number of inputs
without a major increase in the overall device size, compared to traditional
bulk optics. This is particularly important for the upcoming ELT generation of
telescopes currently under construction. We demonstrate the fabrication and
characterization of a novel hybridized photonic interferometer, with 8
simultaneous inputs, forming 28 baselines, the largest amount to-date.
Utilizing different photonic fabrication technologies, we combine a 3D pupil
remapper with a planar 8-port ABCD pairwise beam combiner, along with the
injection optics necessary for telescope use, into a single integrated
monolithic device. We successfully realized a combined device called Dragonfly,
which demonstrates a raw instrumental closure-phase stability down to
$0.9^{\circ}$ over $8\pi$ phase piston error, relating to a detection contrast
of $\sim6.5\times 10^{-4}$ on an Adaptive-Optics corrected 8-m telescope. This
prototype successfully demonstrates advanced hybridization and packaging
techniques necessary for on-sky use for high-contrast detection at small inner
working angles, ideally complementing what can currently be achieved using
coronagraphs.
