All-fiber continuous wave coherent homodyne terahertz spectrometer operating at 1.55 μm wavelengths

Juliette Mangeney

Résumé

Room temperature homodyne and heterodyne THz detections are reported using an 1.55 mum-based THz source. The first experimental demonstration is a continuous wave terahertz homodyne detection, where THz emission is performed with an InGaAs/InP uni-travelling carrier photodiode monolithically integrated with a horn antenna. The coherent homodyne detection is achieved with an ion-irradiated InGaAs photoconductor integrated with a spiral antenna. Experimental results has been obtained up to 700 GHz with a good signal to noise ratio. The second experimental setup is a room temperature heterodyne detection with a Schottky mixer.
