LD09–Over 100 GHz 3-dB down Bandwidth by Direct Modulation of a Coupled Cavity DFB-LD due to Photon-Photon Resonance
This paper reports on 3-dB down bandwidth of 110.6 GHz by direct modulation of a coupled cavity DFB-LD with phase-shifted/uniform gratings due to photon-photon resonance when the injected current is 3.5 times the threshold current.
