The invention is directed to an optically pumped surface-emitting semiconductor laser device having at least one radiation-generating quantum well structure and at least one pump radiation source for optically pumping the quantum well structure, whereby the pump radiation source comprises an edge-emitting semiconductor structure. The radiation-generating quantum well structure and the edge-emitting semiconductor structure are epitaxially grown on a common substrate. A very efficient and uniform optical pumping of the radiation-generating quantum well structure is advantageously possible with this monolithically produced semiconductor laser device. Methods for manufacturing inventive semiconductor laser devices are also specified.

A method for producing an integrated semiconductor component comprising a first semiconductor layer construction for emitting radiation and a second semiconductor layer construction for receiving radiation, wherein a substrate is first provided and a first semiconductor layer sequence containing a radiation-generating region is deposited epitaxially on the substrate. A second semiconductor layer sequence containing a radiation-absorbing region is subsequently deposited epitaxially on the first semiconductor layer sequence. The second semiconductor layer sequence is then patterned in order to uncover a first location and a second location. A first semiconductor layer construction is electrically insulated from a second semiconductor layer construction. Finally, a first contact layer is applied to a free surface of the substrate and a second contact layer is applied at least to the first and second locations for contact-connection.
摘要:
A method for manufacturing an optically pumped surface-emitting semiconductor laser device, wherein a surface-emitting semiconductor laser layer sequence having a quantum confinement structure is applied onto a common substrate. The surface-emitting semiconductor laser layer sequence outside an intended laser region is removed and a region is exposed. An edge-emitting semiconductor layer sequence is applied onto the exposed region over the common substrate, wherein the exposed region is exposed via the removing step, and the exposed region is suitable for transmitting pump radiation into the quantum confinement structure. A current injection path is then formed in the edge-emitting semiconductor layer sequence.
