Inhibition of light tunneling for multichannel excitations in longitudinally modulated waveguide arrays
multichannel excitations longitudinally modulated waveguide arrays
2010/4/1
We consider evolution of multichannel excitations in longitudinally modulated waveguide arrays where refractive index either oscillates out-of-phase in all neighboring waveguides or when it is modulat...
Simplified Slab Waveguide Three-Level Model for Short Length EDFA Pumped at 1.48 µm
Simplified Slab Waveguide Three-Level Model Short Length EDFA 1.48 µ m
2010/10/27
We adopt a three-level scheme for the pump – amplification process in 1.48 m pumped Erbium-Doped Fiber Amplifiers, which reproduces the main experimental features of amplifiers with short and long fi...
High-Power Diffusion Cooling Planar Waveguide CO2 Laser
CO2 Laser dielectric coaxial waveguide
2010/4/19
A diffusion-cooled CO2 laser using a coaxial waveguide is investigated theoretically. The resonator extracting the laser beam consits of two annular plane mirrors enclosing the two ends of the wavegui...
