Surface Plasmon VCSEL with Metal Nanohole Arrays

This paper presents an AlGaAs/GaAs based vertical cavity surface emitting lasers (VCSELs) in which metal nanohole arrays are formed on the top of the distributed Bragg reflector (DBR) as an application of the surface plasmon resonance. Enhanced output power with lower threshold current is achieved as well as the VCSEL serves temperature stable operating current. In addition, the fabricated Surface Plasmon (SP)-VCSEL enables successful control of the polarization angles to any specified directions.
