Developments continue for VCSEL research

AbstractIn recent years the demand for high-performance low-cost optical interconnect components has accelerated. An ideal solution for the transmitter has been found with the development of the vertical-cavity surface-emitting laser (VCSEL). VCSELs show potential for many applications principally due to the ease of producing two-dimensional arrays. One of the most important properties of the VCSEL is its well-defined beam properties, such as circular geometry and its surface-normal emission. VCSELs have been the topic of intense research for several years now. This article will only look at some recently reported results in this field
