A wavelength selectable, controlled chirp, semiconductor laser system is provided. By coupling a passive cavity, including an external output mirror with a selected reflectivity, to the active cavity of a laser device, chirp is reduced by approximately the ratio of the length of the active cavity to the length of the passive cavity. In such a device, changing the length of the passive cavity by manipulating the position of the output mirror allows for selecting an output wavelength of the laser device.
