  New generation exoplanet imagers on large ground-based telescopes are highly
optimised for the detection of young giant exoplanets in the near-infrared, but
they are intrinsically limited for their characterisation by the low spectral
resolution of their integral field spectrographs ($R<100$). High-dispersion
spectroscopy at $R \gg 10^4$ would be a powerful tool for the characterisation
of these planets, but there is currently no high-resolution spectrograph with
extreme adaptive optics and coronagraphy that would enable such
characterisation. With project HiRISE we propose to use fiber coupling to
combine the capabilities of two flagship instruments at the Very Large
Telescope in Chile: the exoplanet imager SPHERE and the high-resolution
spectrograph CRIRES+. The coupling will be implemented at the telescope in
early 2023. We provide a general overview of the implementation of HiRISE, of
its assembly, integration and testing (AIT) phase in Europe, and a brief
assessment of its expected performance based on the final hardware.
