摘要：

A novel AlGaAs/AlAs-TiO2/SiO2 hybrid distributed Bragg reflector is implemented in a planar vertical cavity (top)-surface emitting laser (VCSEL) to control emission (near 850 nm) to a single TEM00-like mode. This structure exhibits >30 dB side-mode suppression ratio and constant divergence (or modal profile) throughout its operating range (i.e., the detrimental effects of thermal lensing inherent in implanted VCSELs are eliminated); moreover, a record low threshold voltage ≅1.6 V, (0.16 V above photon energy) is obtained, without sacrificing the producibility of the standard all-epitaxial structure.© 1995 American Institute of Physics.
