Description
Summary:Continuous wave relative intensity noise (RIN) measurements and pulsed electrical gain switching measurements were performed on vertical cavity surface emitting lasers in order to investigate the high speed potential of these devices. A high resonance frequency–square root of power coefficient of 7.6 GHz/√mW was obtained from the RIN measurements. The gain switched pulses exhibited very fast relaxation oscillations with a maximum observed relaxation oscillation frequency of 71 GHz.
