Integrated-cavity surface-emitting lasers

Abstract

A novel integrated cavity surface emitting laser (ICSEL) is proposed in this paper. An ICSEL integrates two different laser structures. One is an in-plane laser with a short lasing wavelength, and the other is a vertical cavity laser structure with a long lasing wavelength. The in-plane laser is used as the light source for optical pumping the VCSEL. By monolithic integration of both the laser structures, some problems related to electrically pumped VCSELs, especially long wavelength VCSELs, and externally optically pumped VCSELs can be solved.
