Abstract :
A 1.55-μm dual-wavelength distributed feedback (DFB) laser diode array with integrated semiconductor optical amplifiers (SOAs) and multimode interference (MMI) coupler is demonstrated to realize widely tunable continuous-wave terahertz (THz) mode-beating signal generation. DFB lasers, SOAs, MMI coupler and spot-size converters (SSCs) have been integrated on the same InP based substrate. By electrically tuning the wavelength of the two single mode lasing DFB lasers, the chip shows a wide optical mode-beating frequency ranging from 40 GHz to 0.8 THz.
