Optical injection locking and phase-lock loop combined systems.

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 WebOct 15, 2024 · One of them called external injection locking (EIL) where an external laser known as the master laser is used to inject photons to another laser called slave laser to increase the modulation bandwidth. The other scheme uses a reflector to feedback part of the optical power into the laser itself, thus known as self-injection locking (SIL). cigna healthy foods card balance
