1.5 μm 压应变多量子阱增益耦合分布式反馈激光器已在寄生电容极低的半绝缘 InP 衬底上制造，用于研究激光动态特性。获得小信号调制下12.8GHz的最大3dB带宽、调制下20dB下啁啾宽度0.33nm、5Gbit/s NRZ伪随机调制下20dB下啁啾宽度0.33nm、增益切换下20ps的低啁啾短脉冲。 >
1.5 mu m compressive-strained multiquantum-well gain-coupled distributed-feedback lasers have been fabricated on semi-insulating InP substrates with very low parasitic capacitance for studying the laser dynamic characteristics. A maximum 3 dB bandwidth of 12.8 GHz under small signal modulation, a 20 dB down chirping width of 0.33 nm under modulation, a 20 dB down chirping width of 0.33 nm under 5 Gbit/s NRZ pseudorandom modulation, and a low chirping short pulse of 20 ps under gain switching are obtained. >
