Abstract

We demonstrate the generation of microwave and millimeter-wave frequencies from 26 to 100 GHz by heterodyning the output modes of a dual-wavelength fiber laser based on stimulated Brillouin scattering. The output frequency is tunable in steps of 10.3 MHz, equal to the free spectral range of the resonator. The noise properties of the beat frequency indicate a microwave linewidth of <2 Hz. We discuss potential for operation into the terahertz regime.

摘要

我们展示了通过对基于受激布里渊散射的双波长光纤激光器的输出模式进行外差混频，产生26至100 GHz的微波和毫米波频率。输出频率可按10.3 MHz的步长进行调谐，该步长等于谐振器的自由光谱范围。拍频的噪声特性表明微波线宽小于2 Hz。我们讨论了进入太赫兹频段工作的潜力。
