Abstract
Single-mode lasers that operate at high speed with low chirping are indispensable components for 10-Gbit/s direct intensity modulation direct-detection optical communication systems. To improve both modulation speed and chirping characteristics, we introduced multiple-quantum-well (MQW) structures with 10 nm-thick quaternary layers instead of conventional InGaAs wells, since a short carrier lifetime could be expected with wide wells.1 In this paper we are able to report an extremely small chirping width of 0.2 nm under 10 Gbit/s operation with this structure. In addition to achieving these first-rate results, carrier lifetime, differential gains, and alpha parameters were experimentally studied.
