Optical injection locking
WebOptical injection locking (OIL) has been shown to enhance the resonance frequency of the directly-modulated injection-locked laser. In a conventional laser, as bias current is increased, both damping and resonance frequency increase, thereby limiting the maximum bandwidth. In injection-locked lasers, the damping may actually decrease as WebOptical Injection Ratio (R) Fig. 2. Locking bandwidth against optical power ratio R. The circles refer to the measured dynamic limit, the points to the static limit, the diamonds to the onset of bistability. The curves represent the theoretical results: solid line is the dynamic limit; the dotted line is the static limit. the free-running SL.
