Paper Abstract

Filamentation currently limits the amount of diffraction- limited power that can be obtained from broad-area semiconductor amplifiers. This paper examines the filamentation tendencies of a wide input-aperture tapered amplifier. Experimental measurements of filament gain under varying duty-cycle are offered and compared to theory. A numerical simulation of the device operation, which addresses non-uniform current injection, is also presented.
