RESUMO
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 ±16.5 ppm/7 s. The signal quality is also evaluated by performing data transmission, respecting communication standards at 60 GHz using complex modulation formats.
