We report greatly enhanced modulation response of multimode vertical-cavity surface-emitting lasers (MM-VCSELs), for the first time, using optical injection locking. A 3-dB bandwidth of 38 GHz and 54 GHz resonance frequency are achieved using a MM-VCSEL with a 3 GHz freerunning bandwidth. We show that transverse mode selection can be attained with optical injection locking through frequency and spatial detuning.
