The first hexadithienylethene-substituted tris(bipyridine)metal complexes as quadratic NLO photoswitches: combined experimental and DFT studies.

Flip the NLO switch! A straightforward access to hexadithienylethene-based photochromes by using a coordination-chemistry approach through the combination of bis(dithienylethene)bipyridyl ligands and metal ions (M = Zn, Fe) is reported. The…

Monolithic microcavity with carbon nanotubes as active material

We report on the realization of monolithic optical microcavities using a single wall carbon nanotubes doped polymer as active material. Thanks to the control of the polymer thickness, a ne control of the cavity mode energy is achieved, which allows…

Selective Cold Welding of Colloidal Gold Nanorods

A new cold nanowelding technique for cetyltrimethylammonium bromide (CTAB)-stabilized colloidal nanorods in water is reported. This technique leads to the formation of micrometric nanowires by end-to-end self-organization and welding of nanorods…

Stimulated Emission Depletion Microscopy Resolves Individual Nitrogen Vacancy Centers in Diamond Nanocrystals

Nitrogen-vacancy (NV) color centers in nanodiamonds are highly promising for bioimaging and sensing. However, resolving individual NV centers within nanodiamond particles and the controlled addressing and readout of their spin state has remained a…

Magnetometry with nitrogen-vacancy ensembles in diamond based on infrared absorption in a doubly resonant optical cavity

We propose using an optical cavity to enhance the sensitivity of a magnetometer relying on the detection of the spin state of a high-density nitrogen-vacancy ensemble in diamond using infrared optical absorption. The role of the cavity is to obtain…

Theoretical and experimental analysis of intensity noise correlations in an optically pumped, dual-frequency Nd:YAG laser

The spectral behavior of the intensity noise correlations between the two orthogonally polarized modes of a dual-frequency Nd:YAG laser is investigated, both experimentally and theoretically. We show, for different coupling strengths between the two…
