Abstract:
1. A process for producing a surface emitting laser including a surface relief structure provided on laminated semiconductor layer, the process comprising the steps of: forming a first dielectric film on the laminated semiconductor layer; transferring, to the first dielectric film, a first pattern for defining a mesa structure and a second pattern for defining the surface relief structure in the same process; transferring the first pattern and the second pattern to a surface of the laminated semiconductor layers by using the first dielectric film to which the first pattern and the second pattern have been transferred; forming a second dielectric film on the first dielectric film and the semiconductor layers to which the first pattern and the second pattern have been transferred; removing the second dielectric film which has been formed on the semiconductor layers to which the first pattern has been transferred; and forming the mesa structure at a portion where the second dielectric film has been removed.
