Abstract :
We considered the net modal gain and the confinement factors for semiconductor gain and metal loss in a metal-semiconductor-metal waveguide. We found that these confinement factors can have extraordinarily large values and can be gain-dependent and strongly enhanced by pumping in the semiconductor.
