  • Elliptical multi-mesa laser structure
    Patent number: 11955774
    Abstract: Provided is an elliptical multi-mesa laser structure, including a substrate layer, an N-DBR, a functional layer and a P-DBR sequentially arranged from bottom to top. The substrate layer is fixedly connected with an N contact layer. The N-DBR is fixedly connected to a top of the substrate layer, and the N contact layer is arranged around the N-DBR. A space layer is inserted in the N-DBR. The functional layer is fixedly connected to a top of the N-DBR. The P-DBR is fixedly connected to a top of the functional layer, and a top of the P-DBR is fixedly connected with a P contact layer. Another space layer is inserted into the P-DBR.
