Resonant waveguide gratings (RWGs) are thin-film structures, where coupled modesinterfere with the diffracted incoming wave and produce strong angular and spectral filtering. The combination of two finite-length and impedance matched RWGs allows the creati ...

Subwavelength Focusing of Bloch Surface Waves

Hans Peter Herzig, Myun Sik Kim, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani

Microsized spheres can focus light into subwavelength spatial domains, a phenomenon called photonic nanojet. Even though well studied in three-dimensional (3D) configurations, only a few attempts have been reported to observe similar phenomena in two-dimen ...

Nickel-catalyzed diastereoselective alkyl-alkyl Kumada coupling

Xile Hu, Peng Ren, Pablo Marcelo Perez Garcia, Alessio Orsino

A nickel pincer complex is found to catalyze alkyl–alkyl Kumada coupling reactions of 1,3- and 1,4-substituted cyclohexyl halides and tetrahydropyrans with an excellent diastereoselectivity. The mechanistic investigation of the coupling reactions provides ...

Optical Gas-Phase Frequency References Based on Photonic Crystal Technology

Isabelle Dicaire

Optical frequency references are devices providing well-defined and stable optical frequency responses to incoming radiation for applications such as high-precision spectroscopy and optical fibre communications. To stabilise the emission frequency of laser ...
