Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, EarlyView.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Cross‐Phase Modulation via Time‐Varying Epsilon‐Near‐Zero Metasurfaces
Advanced Optical Materials, EarlyView.Time‐varying epsilon‐near‐zero metasurfaces are shown to enable cross‐phase modulation beyond conventional ENZ excitation. By engineering dual absorption bands and exploiting oblique ultrafast pumping, large and broadband frequency translations are achieved at low pump energies.

Advanced Optical Materials, EarlyView.Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.
