摘要：

We report on the high-resolution linewidth measurements of proton-implanted InGaAs-GaAs VCSEL'S employing the delayed self-heterodyne method. Devices with 16-mu m active diameter exhibit record low linewidths of 20 MHz and 4-MHz residual linewidth. The linewidth enhancement factor is accurately determined from the ratio of induced phase to amplitude modulation indexes.
