“…They demonstrate high reflection, ultra-strong optical nonlinearity and infinite phase velocity of the propagating light, and are expected to provide an unprecedented pathway to optical device design. As a typical ENZ material, indium tin oxide (ITO) has been extensively studied as the transparent electrodes, biological sensors and solar batteries, etc [24][25][26]. In the near-infrared (NIR) wavelength region, its permittivity can close to zero [23,27].…”

Indium tin oxide nanocolumns array (ITO-NCs-A), a typical epsilon-near-zero material, was prepared by chemical vapor deposition method. Due to the strong third-order optical nonlinearity and large refractive index change of the ITO-NCs-A at ~1.06 µm, we used it as a passively Q-switched device and obtained a stable 1.06 µm Nd:BGO pulsed laser for the first time, to the best of our knowledge. The maximum average output power is 152 mW, the maximum repetition rate is 126.1 kHz, the shortest pulse width is 579.6 ns, and the corresponding single pulse energy and pulse peak power are 1.21 µJ and 2.08 W, respectively. This work indicates that ITO-NCs-A has promising applications in ultrafast photonics and is expected to provide a more reliable solution for optical modulators in pulsed lasers.

Controlling growth of self-propagating molecular assemblies

A series of six self-propagating molecular assemblies (SPMAs) were generated by alternative solutiondeposition of ruthenium polypyridyl complexes and d 8 palladium and platinum salts on glass and silicon substrates. The d 6 polypyridyl complexes have three pyridine units available for forming networks by coordination to the metal salts. This two-step film growth process is fast (15 min/step) and can be carried out conveniently under ambient conditions in air. The reactivity of the common metal salts (ML 2 X 2 : M ¼ Pd, X ¼ Cl, L ¼ PhCN, 1 / 2 1,5-cyclooctadiene (COD), SMe 2 and M ¼ Pt, X ¼ Cl, Br, I, L ¼ PhCN) is a dominant factor in the film growth. Although the assembly structures are comparable, their exponential growth can be controlled by varying the metals salts. The co-ligands, halides, and metal centers can be used to control the film thicknesses and light absorption intensities of the metal-to-ligand charge transfer (MLCT) bands by a factor of $3.5 for 13 deposition steps, whereas the surface morphologies and molecular densities of the SPMAs are similar. The surface-confined assemblies have been characterized using a combination of optical (UV/Vis, ellipsometry) spectroscopy, atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and synchrotron X-ray reflectivity (XRR).
