摘要

介绍了一种采用混合集成技术的小型低成本4×25-Gb/s收发光子组件（TOSA/ROSA）的设计与制造。TOSA和ROSA在无热电冷却器（TEC）情况下可满足粗波分复用（CWDM）应用。光学子组件（OSA）封装外壳的物理尺寸为11.5 mm×5.4 mm×5.4 mm。采用石英基阵列波导光栅（AWG）芯片作为TOSA和ROSA波长的复用和解复用器件。选择O波段特定通道波长。在TOSA中，重建等效啁啾（REC）技术能实现对4个1.3µm离散直接调制激光器（DML）芯片波长的精确控制。在背靠背传输试验中，TOSA和ROSA组成链路中各通道误码率在满足100G-4WDM-10标准下灵敏度分别为−7.1、−6.6、−6.2和−5.1 dBm。采样示波器的数据经过处理后能得到清晰端正的眼图。

Abstract

The design and fabrication of a compact and low-cost 4×25-Gb/s transmitter optical sub-assembly (TOSA) and receiver optical sub-assembly (ROSA) using a hybrid integrated technique are reported. TOSA and ROSA are developed without thermoelectric cooler for coarse wavelength division multiplexing applications. Physical dimension of the packaged optical sub-assembly is limited to 11.5 mm×5.4 mm×5.4 mm. The design of TOSA and ROSA is employed using a silica-based arrayed waveguide grating chip to select the specific channel wavelength at O-band. In TOSA

the wavelength of four 1.3-μm discrete directly modulated laser chips is well controlled based on the reconstruction equivalent chirp technique. In the back-to-back transmission test

bit error rates for all lanes of cascade of the TOSA and ROSA are small. A clear opening eye diagram is obtained.
