展示了高速直接调制850 nm氧化物限制垂直腔面发射激光器(VCSEL)的结果。优化设计应变InGaAs/AlGaAs量子阱以实现高微分增益,通过表面刻蚀来调节光子寿命实现响应平坦化。研制的氧化物孔径约7 µm的VCSEL具有平坦的频率响应,3 dB调制带宽为24 GHz,相对噪声强度值-155 dB/Hz,未采用任何预加重和均衡技术情况下PAM4调制数据传输速率达80 Gb/s。
We present the results of a high-speed direct modulation 850 nm oxide confined vertical cavity surface emitting laser(VCSEL),optimize the design of strain InGaAs/AlGaAs quantum wells to achieve high differential gain, and adjust the photon lifetime through surface etching to achieve response flattening. The developed VCSEL with an oxide aperture of about 7 µm has a flat frequency response, a 3 dB modulation bandwidth of 24 GHz, and a relative noise intensity value of -155 dB/Hz. Without any pre-emphasis and equalization technology, the PAM4 modulation data transmission rate can reach 80 Gb/s.
