Abstract
We demonstrate a novel modulation technique with a vertical-cavity sur face-emitting laser (VCSEL) using an intracavity embedded voltage-bias ed quantum well absorber, We achieved a -3-dB small-signal bandwidth o f 9 GHz and a response of 7 GHz/root mA by modulation of the absorber, Our calculations show that this technique introduces significantly le ss chirp at higher frequencies than direct current modulation.
