We fabricate z-cut LiNbO3 nonlinear photonic crystal with two-dimensional dodecagonal superlattice by applying high voltage pulses.By using collinear quasi-phas
A three-level ladder-type system with vacuum-induced coherence and incoherent pumping is studied to obtain a high refractive index without absorption.It is show
The origin of magneto-conductance (MC) in tri-(8-hydroxyquinoline)-aluminum (Alq3)-based organic light emitting diodes is investigated.Our results clearly show
We find for the first time that a model Hamiltonian of s-wave superconductors in the presence of spin-orbit interactions and a Zeeman field is exactly solvable.
We report a high power high beam quality quasi-continuous-wave (QCW) diode-end-pumped Nd:YAG slab amplifier at 1319nm.The strongest 1064 nm parasitic oscillatio
We derive an alteate analytical expression for the optimum dimensions of an electromagnetic undulator with a finite permeability lamination core.The analytical
