Clementine star tracker view of the Moon and Venus in the distance. The Clementine High-Resolution Camera consisted of a telescope with an image intensifier and a frame-transfer CCD imager. The imaging system was designed to study selected portions of the surfaces of the Moon and the near-Earth asteroid 1620 Geographos, although the asteroid ...
The optical materials, photonics and systems laboratory (LMOPS) [1] gathers researchers from Lorraine university [2] and from CentraleSupélec [3],, [4] in the cities of Metz, Saint-Avold and Thionville. The research themes lie in the fields of materials in general and optical materials more specifically, non linear optics, optical sensors and ...
Photonic topological phases are classical electromagnetic wave analogues of electronic topological phases studied in condensed matter physics. Similar to their electronic counterparts, they, can provide robust unidirectional channels for light propagation. [2] The field that studies these phases of light is referred to as topological photonics.
Adding non-Hermiticity (such as dichroism) to photonic systems which present Dirac points transforms these degeneracy points into pairs of exceptional points. This has been demonstrated experimentally in numerous photonic systems such as microcavities [ 3 ] and photonic crystals . [ 4 ]
In photonics and quantum optics, photonic quantum sensing leverages entanglement, single photons and squeezed states to perform extremely precise measurements. Optical sensing makes use of continuously variable quantum systems such as different degrees of freedom of the electromagnetic field, vibrational modes of solids, and Bose–Einstein condensates. [5]
Unlike electronic integration where silicon is the dominant material, system photonic integrated circuits have been fabricated from a variety of material systems, including electro-optic crystals such as lithium niobate, silica on silicon, silicon on insulator, various polymers, and semiconductor materials which are used to make semiconductor lasers such as GaAs and InP.
Clementine 2 was a proposed asteroid-interception mission that was intended to fly by two near-Earth asteroids, 433 Eros and 4179 Toutatis planned by NASA. [2]The probe impact at Toutatis was needed to obtain the dynamic strength of surface material and data on the properties of the regolith and on stratification below the surface, and potentially allowed the measurement of thermal diffusivity ...
Her research also looks at how to integrate plasmonic particles with other photonic systems. The Halas groups collaborates with the Energy Frontier Research Center at the National Renewable Energy Laboratory to study using plasmonics to improve the energy harvesting properties of semiconductor quantum dots and nanocrystals .
