Abstract
A method to provide user selected tunability for multi-section lasers manufactured for the telecommunication industry is disclosed. Extending the tunability of the laser to be user selectable provides a means to use the technology in other applications such as gas sensing or optical component testing. The combination of the broad tuning range with rapid wavelength selection will permit a reduction in the number of DFB lasers used in multiplexed systems thereby reducing system cost and complexity.
