ECE Professor Daniel Feezell Publishes GaN VCSEL Review in Compound Semiconductor
Daniel Feezell’s six-page, full-color article entitled “The Evolving GaN VCSEL” was published in this month’s Compound Semiconductor (Vol 20, No. 1), a trade magazine based in the UK with an international print circulation of 60,000.

(A compound semiconductor is made from two or more elements — in contrast to a normal semiconductor which is made from silicon.)
This review provides an overview of progress and challenges for GaN-based vertical-cavity surface-emitting lasers (VCSELs), which typically emit light in the violet to green region of the optical spectrum. These devices are finding applications in high-density optical data storage, chemical and biological sensing, and high-resolution printing.
Dr. Feezell’s article is important because of the far-reaching exposure that his words will receive: A paper that is written at a conference only reaches a select audience. This article, however, has the potential of capturing the attention of engineers and their management on a global scale.
The Magazine Compound Semiconductor touts itself as being the “leading provider of news, analysis, opinion, information and services for the worldwide Compound Semiconductor industry since 1995.”
