Abstract

We demonstrate a new nonlinearity reduction method in directly modulated distributed feedback (DFB) semiconductor lasers. By injecting external light into a DFB laser sidemode, the nonlinear distortion of the laser is significantly reduced. Compared to the previously reported main-mode optical injection locking scheme, greater distortion suppression and a wider stable locking range can be achieved.
