Gigahertz modulation of tunable terahertz radiation from photomixers driven at telecom wavelengths
M. Martin, J. Mangeney, P. Crozat, Y. Chassagneux, R. Colombelli et al.
Here, we report the gigahertz-rate modulation of a tunable terahertz carrier. Terahertz radiation, tunable from 300 GHz to 1.2 THz, is generated by mixing two telecom lasers with an offset frequency in an ultrafast InGaAs photoconductive device coupled to a broadband antenna. The microwave modulatio ... [Appl. Phys. Lett. 93, 131112 (2008)] published Fri Oct 3, 2008.
