GaN-based blue vertical-cavity surface-emitting lasers

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


In this chapter we provide a brief review of the optical and electrical pumped GaN-based vertical-cavity surface-emitting lasers from the fabrication technology to output characteristics analysis. Three types of VCSEL structures are discussed in the following paragraph including their pros and cons among design and process difficulties. First type is fully epitaxial VCSEL structure, second one is the hybrid microcavity consists of a bottom epitaxial DBR and a top dielectric DBR, and third one is vertical resonator composes dielectric top and bottom DBR. We also present several examples of GaN-based VCSELs achieve laser action under optical and electrical pumping at room temperature.
