Fiber Brillouin amplifier intensity noise is investigated experimentally for a distributed feedback and external cavity diode laser. Since relative intensity noise is a serious performance limitation in Brillouin amplification applications, a detaile

The success in conquering the terahertz (THz) gap is subject to some facts such as maximizing the emitted power. Traditionally resonant antenna designs for continuous-wave (CW) THz photomixing include a RF choke to compensate the capacitive part of t

This paper reviews recent advances in the development of high-speed 1.55-/spl mu/m traveling-wave p-i-n photodetectors (TWPD) for photonic millimeter-wave and submillimeter-wave local oscillators. We first discuss the basic physics and performances o

We developed an all-fiber-based continuous-wave terahertz spectrometer based on optoelectronic signal generation and detection. The spectrometer has a very high spectral resolution in the MHz range over the whole tuning range from 50 GHz to 1750 GHz.

Terahertz radiation bears great potential in imaging and spectroscopy. One established method of generating tunable continuous-wave (cw) terahertz light is optical heterodyning: a photomixer is irradiated with two near-infrared lasers of adjacent wav

Continuous-wave terahertz (THz) radiation was generated by photomixing two modes of a titanium sapphire laser. The laser was induced to oscillate on two modes by placing a Fabry-Perot etalon in the laser resonator. The frequency of terahertz radiatio

We report on photonic technologies developed at the MPI fur Radioastronomy and the Research Center Julich to generate Terahertz Local Oscillator reference signals for use on e.g. ALMA/APEX and SOFIA. The principle is to mix two (NIR) laser colours in

In a continuous-wave terahertz system based on photomixing, the measured amplitude of the terahertz signal shows an uncertainty due to drifts of the responsivities of the photomixers and of the optical power illuminating the photomixers. We report on
