Inventor: OH MYEONG SEOK
IPC: H01S5/30
Filed: 2001-05-29
Abstract: PURPOSE: A laser diode and a fabrication method thereof are provided, which has a high output power and can be fabricated easily and reproducibly. CONSTITUTION: A N type clad layer(30) is formed on a N type GaAs substrate(10), and a buffer layer(20) is formed on the N type clad layer. An active layer(41) is formed on the buffer layer. A P type clad layer(50) is formed on the active layer. A composite material comprising the N type or P type clad layer is diffused into the active layer by annealing a part of the active layer through a laser annealing. A current blocking layer(60) revealing a part of the P type clad layer is formed. A P type GaAs cap layer(70) is formed. And a N type metal layer(90) and a P type metal layer(80) are formed below the substrate and above the P type GaAs cap layer.
