9.7 GHz small-signal bandwidth of three-quantum well GalnNAs/GaAs laser diodes operating at 1.35 mu m
01 April 2004
High frequency characterisation of three-quantum well GaInNAs/ GaAs lasers operating at 1.35 mum is reported. A relaxation frequency as high as 7.4 GHz and a 9.7 GHz small-signal bandwidth are demonstrated, indicating the potential for high bit rate (10 Gbit/s) direct modulation of these dilute nitrides on GaAs devices.
