| 英文摘要 | A method of manufacturing a coherent light generator, especially a vertical cavity surface emitting laser (VCSEL), includes a gallium based semiconductor alloy substrate, a first DBR stack over the substrate, a first n-type clad layer over the first DBR stack, an active region containing quantum wells over the first n-type clad, a tunnel junction having an n-type and a p-type material and a boundary over the active region so that there is a standing wave null at an operating wavelength at the n-type/p-type boundary in the tunnel junction, a second n-type clad layer over the tunnel junction, an oxide aperture at least partially installed in the second n-type clad layer, and the second DBR stack over the second n-type clad of the coherent light generator. The novel VCSEL provides minimized internal optical absorption and has a low electrical resistance. |
