The ONDA nanomaterials platform

The ONDA nanomaterials platform brings together the resources needed to design and characterize nanostructured components for infrared applications.

These resources range from structural characterization (infrared ellipsometer, electron microscope), optical property measurements (FTIR spectrometers, coupled to a microscope, tunable laser and OPO sources) and optoelectronic properties (cryostat, spectral and angular response measurements). Our resources include both off-the-shelf instruments and innovative benches developed specifically for the purpose.

Nanostructure design tools (electromagnetic simulation and optimization code) are tested and validated experimentally. Wavelengths range from near infrared to terahertz.

ONDA offers (i) new nanotechnology-based solutions for controlling the optical properties of surfaces. The nano-antennas and metamaterials designed by our researchers are characterized at ONDA in order to control their absorption, infrared emission and electromagnetic field localization properties.

This work relies in particular on academic collaborations (IOGS/LCF, CNRS/C2N, École polytechnique) as well as industrial ones (Thales TRT, ULIS) (ii) new functions for photodetection. The work carried out at ONDA addresses major industrial challenges: providing spectral or polarizing functions, raising the operating temperature of detectors, improving the sensitivity or selectivity of sensors for gases or explosive molecules.

This work is also supported by a network of academic (CNRS/C2N, Université de Montpellier/IES, CEA) and industrial (Sofradir, ULIS) collaborations.

ONDA will enable ONERA to strengthen its position as a bridge between civilian and defense applications and the academic world.
