Temporal locking of pulses in injection locked oscillators.

ABSTRACT: We demonstrate a novel injection-locking effect in oscillators, which is obtained in both the time and frequency domains. The "temporal-locked" oscillator generates an ultra-low phase noise continuous-wave (CW) signal, accompanied by an ordered train of short [Formula: see text] phase pulses with precise timing, where both signals are phase-locked to an external sinusoidal source. Remarkably, even when the cavity delay drifts, the period of the temporal-locked pulses remains constant. Furthermore, the instantaneous phase and the timing of the minimum and maximum amplitudes within part of the pulse remain approximately constant. These unexpected results stem from the nonlinear effect of strong injection on the waveform of the phase pulses. In particular, this effect leads to the self-adapta
