We present the first study of the hybridizing effect of different left-handed metamaterials (LHM) based on S-shaped and Ω-shaped resonators. Three different cases of hybridizing are investigated, ten configurations of various hybrid ratio are simulated, fabricated and measured, and a series of different left-handed passbands is obtained, showing that the left-handed passband of the proposed hybrid...
Upconversion luminescence and their mechanisms of the Er 3+ and Tm 3+ codoped tellurite glasses were investigated under both the 975 and 800 nm excitation. By Tm 3+ codoping, the Er 3+ green emission corresponding to the ( 4 S 3/2 , 2 H 11/2 ) → 4 I 15/2 transitions was quenched, while the red emission corresponding to...
