Abstract(in English) | Because of recent significant increase of data traffic, much attention has been paid to high-speed optical transmitters. In order to realize high-speed directly modulated lasers with low driving current, we have investigated AlGaInAs-based multiple-quantum-well (MQW) lasers combined with semi-insulating buried-heterostructure (SI-BH). In this paper, we report 1.55μm and 1.3-μm AlGaInAs-MQW SI-BH distributed reflector (DR) lasers with passive reflectors on both sides of very short active region. We successfully achieved very high slope values of relaxation oscillation frequency(fr) and realized 40-Gbps direct modulation with low driving-current. |
