Continuous-wave (CW) THz generation from InGaAs based photomixers has been demonstrated by using a tunable dual-wavelength 3-section DFB laser diode as the optical beat source. The wavelength of each lasing mode can be tuned by adjusting currents in micro-heaters which are fabricated on the top of the each DFB section. The CW THz frequency emitted from the InGaAs photomixers is continuously tuned...
We demonstrate simultaneous optical clock extraction and wavelength-conversion from NRZ in MZ-IWC. PRZ extracted from pump using optical filter. By injection-locking self-pulsation LD using PRZ, optical clock obtained. Simultaneously, we obtained wavelength-converted signal from probe.
