We introduce an approach to stabilizing the wavelength of a semiconductor laser employing a voltage-tunable photodetector. The latter provides a bipolar error signal driving a feedback loop for the laser retuning. We demonstrate wavelength stabilization within +/-25 pm in the 1.55 mum window. Performances, system compactness, and integrability make the approach quite appealing for use in dense wavelength division multiplexing networks. (C) 2002 American Institute of Physics.

Abstract

The latter provides a bipolar error signal driving a feedback loop for the laser retuning. We demonstrate wavelength stabilization within +/-25 pm in the 1.55 mum window. Performances, system compactness, and integrability make the approach quite appealing for use in dense wavelength division multiplexing networks.
