Abstract

Intracavity contacted vertical-cavity lasers are a class of index-guided surface-emitting lasers which use thin p-type and n-type layers within the optical cavity to supply current to the active region. The design allows the use of two ring contacts on the same surface, top or bottom emission, and semi-insulating substrates. A dielectric aperture is used to provide both current constriction and optical confinement. The models used to design the laser's continuous wave characteristics are discussed and the calculated characteristics are compared with experimental measurements. The microwave modulation response of lasers of varying diameter has been measured with wafer-level probing techniques. The very high modulation efficiency of the lasers, up to 5.7 GHz/(root)mA, shows good agreement with theory. The analysis indicates the directions and challenges for the realization of very high-speed, low-power surface-emitting lasers.
