This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets. For this work the Leiden EXoplanet Instrument (LEXI) was build, which is a visiting instrument for the William Herschel Telescope on La Palma. LEXI was used a pathfinder for testing new technology. The potential of these technqiues have been demonstrated with the observations of PDS 70 by the MUSE instruments, where we have characterized a proto-planet and found a second proto-planet in the same system. The proposed techniques in this thesis can be implemented on future instruments and telescopes for the characterization of exoplanets.
