Abstract
A vertical cavity surface emitting laser emitting at about 1.3 microns while being optically pumped by a vertical cavity surface emitting laser emitting at about 810 nanometers characterized in that the resonant cavities of the two lasers are coupled to increase the effectiveness of the pumping light to stimulate emission from the gain medium of the long-wavelength medium. The two lasers are formed in a multilayer stack of which all the layers are epitaxial except for the layers at the top of the stack that serve as a broad band output mirror and the upper bounding of the long wavelength laser.
