• Mode-locking — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s). The basis of the technique is to induce a fixed phase… …   Wikipedia

• Injection locking — is a high frequency (usually RF, but possibly microwave and optical) phenomenon where an oscillator directly synchronizes to another high frequency signal. In the case of a VCO an injection locking signal may override its low frequency control… …   Wikipedia

• Injection locked frequency divider — In electronics, an injection locked frequency divider (ILFD) is a frequency divider that operates similarly to an injection locked oscillator. In an injection locked frequency divider, the frequency of the input signal is a multiple (or fraction) …   Wikipedia
