Project description
Developing nano-optics for ultra-fast microscopes
Using extreme ultraviolet (EUV) light for microscopy offers hope for imaging with high spatiotemporal resolution and excellent material contrast. However, it is held back by the complicated handling of EUV radiation. Funded by the European Innovation Council, the EUVORAM project aims to demonstrate that meta-optical devices are feasible within the EUV domain by implementing a cutting-edge design technique. It will also demonstrate that meta-optical devices can address the current insufficient supply of transmissive EUV optics. Ultimately, EUVORAM will construct a microscope that merges attosecond time and nanometre spatial resolution to follow light-matter interaction in nanodevices.
Objective
Extreme ultraviolet (EUV) light sources have matured, both in brightness, as well as in producing ever shorter attosecond light pulses. Contrary, transmissive EUV optics remain sparse due to material absorption. Thus, EUV microscopy today focuses mainly on lensless techniques or secondary observables such as photoelectrons. EUVORAM (Extreme-Ultraviolet Meta-Optics for Attosecond Microscopy) will experimentally demonstrate that meta-optical devices are realizable in the EUV using a novel design approach and that they can solve the current lack of transmissive EUV optics. By emulating the spatial phase profiles of aspheric lenses, we will fabricate focusing meta-optics yielding near-diffraction limited microfoci in the EUV. In combination with contemporary attosecond pulse sources based on laser-driven high-harmonic generation, these meta-lenses will enable high-numerical-aperture EUV focusing that maintains attosecond pulse durations. EUVORAM will exploit this capacity to build a light microscope that unifies attosecond time and nanometer spatial resolution. After its demonstration, we will apply this microscope to isolate the ultrafast hot electron dynamics and sub-nanometer charge transfers in individual plasmonic core@shell nanoparticles using spatially resolved attosecond transient absorption spectroscopy.
EUVORAM will be one of the first projects connecting attosecond science and dielectric meta-surfaces. The planned EUV meta-optics and their novel design will undercut the current short-wavelength limit of meta-surface optics by a factor of four and thus directly redefine the state-of-the-art. The project will push lens-based microscopy to unprecedented time resolutions and at the same time allow hyperspectral attosecond imaging. The latter will free attosecond experiments from observing ensemble averages and provide spatially resolved insight in the light-matter-interaction of photonic nanodevices.
