| 英文摘要 | A vertical cavity surface emitting semiconductor laser is formed with a multilayer structure on a semiconductor substrate that includes an active region layer, a central core, and an antiresonant reflecting waveguide ring surrounding the central core. The ring includes a region formed to have an effective higher index than the central core and sized to provide antiresonant lateral waveguiding confinement of a fundamental mode wavelength. Reflectors formed above and below the active region layer provide vertical confinement. The antiresonant reflecting ring may be formed either as a full ARROW structure including a quarter wavelength high effective index region and a quarter wavelength low effective index region or as a simplified ARROW structure having a single quarter wavelength high effective index region. The antiresonant reflecting ring provides efficient lateral confinement of the fundamental mode while allowing lateral leakage of higher modes to substantially suppress these modes, resulting in substantially single mode operation at relatively high powers. |
