Abstract

A two-dimensional vertical-cavity surface emitting laser array is expected to be a key device for parallel lightwave transmission and optical interconnection systems. This paper analyzes the number of channelsin a two-dimensional vertical-cavity surface emitting laser array, from the viewpoint of the electric power consumption and the light-output. Dependence of the number of channels on several parameters is examined. It was found that high slope efficiency and low electrical resistance lead to a large number of channels, and the contribution of threshold reduction is small if the threshold current is of the order of 100 mu A or less. It is also shown that if each channel is composed of plural elements, the number of channels increases.
