Abstract

Low phase noise and tunable THz-signals from 300 GHz to 1 THz are obtained with a combination of a unitravelling carrier photodiode and a solid-state dual-frequency laser at 1.5 μm. The spectral purity is precisely characterized. Phase noises as low as -20 dBc/Hz at 1 kHz offset from the carrier frequency and an Allan deviation of 3·10^-5 on 100 s are obtained.
