Optoelectronic down-conversion of a THz optical beatnote to a RF intermediate frequency is performed with a standard Mach-Zehnder modulator followed by a zero dispersion-slope fiber. The two interleaved optical spectra obtained by four-wave mixing are shown to contain more than 75 harmonics enabling to conveniently recover the phase noise of a beatnote at 770 GHz at around 500 MHz. This four-wave...
Optoelectronic down-conversion of a terahertz optical beatnote to a RF intermediate frequency is performed with a standard Mach-Zehnder modulator followed by a zero dispersion-slope highly nonlinear fiber. The two interleaved optical combs obtained by four-wave mixing are shown to contain more than 75 harmonics enabling to conveniently recover the phase noise of a beatnote at 770 GHz at \(\sim 500\) ...
Down-conversion from a THz beat generated by a two-frequency solid-state laser to a RF intermediate frequency is performed with a zero dispersion-slope fiber. The two interleaved four-wave mixing spectra contain more than 75 harmonics.
A narrow linewidth THz source is reported. A beatnote provided by a dual-frequency laser is sent into a unitravelling carrier photodiode, and radiated by a transverse-electromagnetic-horn antenna. The emitted THz signal is detected by a subharmonic mixer coupled to an electrical spectrum analyzer. The measured linewidth is better than 30 kHz and tunable from DC to 770 GHz with a minimum 30 dB dynamic...
