Abstract
Through the reduction of mirror-resistance of vertical-cavity surface-emitting lasers, the optical bandwidth of 22.5 GHz is successfully achieved by implementation of zinc-diffusion process. It shows that lower mirror-resistance provides better transmission quality under similar optical bandwidth. With 20 ohm resistance reduction, the bandwidth limitation by electrical parasitics can be effectively improved from 6.4 to 14.71 GHz confirmed by the small-signal extraction results.
