In this Letter, the impact of thermal coupling between two glass laser cavities on a heterodyned signal for millimeter-wave frequency generation is presented. In addition to a narrow heterodyne linewidth estimated to be lower than 1 kHz, the frequency drift is reduced to $\pm 16.5\mathrm{ppm}/7\mathrm{s}$. The signal quality is also evaluated by performing data transmission, respecting communication standards at 60 GHz using complex modulation formats.

热耦合对玻璃上使用两个自由运行的DFB激光器产生的MMW载体的影响

在这封信中，介绍了两个玻璃激光腔之间的热耦合对产生毫米波频率的外差信号的影响。除了窄的外差线宽估计低于1 kHz，频率漂移还可以降低到$\pm 16.5\mathrm{百万分之几}/7\mathrm{s}$。还可以通过执行数据传输来评估信号质量，并遵守60 GHz使用复杂调制格式的通信标准。
