Abstract: Disclosed is a directly-coupled wavelength-tunable external cavity laser including a gain medium that generates an optical signal by an applied bias current; an optical waveguide structure that is coupled to the gain medium to form a minor surface and causes lasing in the mirror surface when the applied bias current has a threshold or higher; and a radio frequency transmission medium that adds a radio frequency signal to the applied bias current to adjust an operating speed of the optical signal.
