摘要

本文介绍了一种二维VCSEL阵列的驱动电路。驱动电路采用新颖的低阻抗分流共面波导，最大限度地减少通道间串扰。为了证明我们的方法，设计并制作了一个10 Gb/s的GaAs HBT驱动电路。测量和模拟结果表明，与使用传统微带和共面波导的类似设计相比，串扰改善了20 dB。据我们所知，在公开文献中，二维VCSEL阵列驱动器的串扰是最低的。

A single-ended laser driver with shunt coplanar waveguide for reduced crosstalk

This paper describes a driver circuit for two-dimensional VCSEL arrays. The driver circuit uses a novel low-impedance shunt coplanar waveguide to minimize interchannel crosstalk. To demonstrate our approach, a 10 Gb/s GaAs HBT driver circuit has been designed and fabricated. Both measured and simulated results show a 20 dB crosstalk improvement compared to similar designs using conventional microstrip and coplanar waveguides. To the best of our knowledge, the crosstalk is the lowest reported for a two-dimensional VCSEL array driver in the open literature.
