We report the design, fabrication and characterization of a 1.55-μm dual-wavelength Distributed Bragg Reflector (DBR) laser photonic integrated circuit (PIC) chip for continuous-waves (CW) terahertz generation. The PIC chip consists of a pair of parallel DBR lasers with integrated semiconductor optical amplifiers (SOA), and a multimode interference (MMI) coupler for combining the two wavelength channels into a single output waveguide. A room temperature continuous wave THz tuning range of 0.06 THz – 0.71 THz was obtained through optical heterodyne technique.
