Abstract
We present the idea to design the surface defect structure of the VCSEL to induce various vertical emission transverse modes, including high-order whispering gallery modes, whispering gallery-like modes, chaotic modes and unidirectional emitting patterns in simulations, as well as in experiment*. Moreover, modulating the phase difference of the superposition of whispering gallery and dynamical localized modes, which correspond to the stable and unstable periodic orbits, respectively, are reported to control lasing characteristics. *: The experiments are performed by Graduate School of Optoelectronics, National Yunlin University of Science and Technology, Yunlin, 640 Taiwan.
