Modulation characteristics enhancement by mutual injection locking of monolithically integrated distributed feedback (DFB) lasers is studied. Locking bistability in mutually coupled integrated lasers is observed. Resonance frequency as high as 34.3 GHz is recorded, corresponding to more than fivefold enhancement over the relaxation oscillation frequency at free running state. The mutually injection-locked...
Modulation characteristics enhancement by mutual injection locking of monolithically integrated lasers is demonstrated. Resonance frequency as high as 34.3 GHz is recorded. The nonlinearity and chirp performances are simultaneously improved compared with free running state.
A novel approach for millimeter-wave generation is proposed and demonstrated by suppressing modulation induced chaos in an integrated coupled DFB laser. Millimeter-wave carrier with high spectral purity is generated at ten times the modulation frequency.
We report millimeter-wave generation by an integrated dual wavelength laser diode based on optical sideband injection locking. Low phase noise millimeter-wave carrier at 42 GHz has been generated from 5.25 GHz modulation signal.
