High-power and high-speed performance of gain-coupled 1.3 μm strained-layer MQW DFB lasers

Abstract
Form only given. High power and high modulation bandwidth 1.3 μm DFB InGaAsP QW lasers with gain coupling in a strained-layer MQW active region are reported for the first time. Due to the nature of the gain coupling effect, devices show lasing spectra with a consistently high single mode yield Author(s) Lu, H.
