A new receiver drastically increases the signal-to-noise ratio of 1.5mum cw THz photomixing systems. The obtained SNR of 105 dB at 100 GHz and 45 dB at 2 THz are the highest values reported in literature and superior to 800 nm setups. This is a milestone in the evolution of cw THz photomixing systems.
