Abstract
The authors demonstrate an optical injection technique for stabilising the frequency and reducing the phase noise of the millimetre-wave signal generated by a passively modelocked monolithic DBR laser. The optical injection signal is obtained by externally modulating a CW laser using the double sideband suppressed carrier (DSBSC) modulation technique. A locking range of 170 MHz is achieved with an injection optical power of less than 50 µW.Keywords
