title: Nonlinear optical interaction in semiconductor lasers due to population pulsations.
abstract: Population pulsations are demonstrated as a basic mechanism for nonlinear optical interaction in a semiconductor laser by detecting the optical beat frequency in the noise spectrum of the injection current.
