We present a novel application of optical tunneling in the context ofhigh-angular resolution, high-contrast techniques with the aim of improvingdirect imaging capabilities of faint companions in the vicinity of brightstars. In contrast to existing techniques like coronagraphy, we applywell-established techniques from integrated optics to exclusively extinct avery narrow angular direction coming from the sky. This extinction is achievedin the pupil plane and does not suffer from diffraction pattern residuals. Wegive a comprehensive presentation of the underlying theory as well as firstlaboratory results.

A novel high-contrast imaging technique based on optical tunneling to search for faint companions around bright stars at the limit of diffraction
