Immense optical field enhancement was predicted to occur for the Berreman mode in ultrathin films at frequencies in the vicinity of epsilon-near-zero (ENZ). Here, we report the first experimental ...
We have experimentally demonstrated efficient second harmonic generation of 532 nm from polarization maintaining Yb-doped CW fiber laser using periodically-poled lithium niobate. The scheme is simple ...
In this paper, an equivalent model that can achieve optimal-power voltage waveform and second harmonic load of transistor is proposed. In steady state, the transistor is transformed to a Norton ...
