Dual frequency Brillouin fiber laser and 1.55 µm photomixer for highly coherent THz wave generation

Résumé

Using a dual frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilo-Hertz level sub-millimeter wave emission. This system does not require any electrical synthesizer, and low cost telecom components are used to achieve very simple source architecture. The THz photomixer is composed of a uni-travelling carrier photodiode integrated with an antenna. A ~ 1 kHz linewidth emission at 316 GHz is observed, with a signal to noise ratio >; 65 dB.
