The authors describe planar, gain-guided vertical-cavity surface emitting lasers with a modulation bandwidth of 14 GHz. This bandwidth is reached at a drive current of only 8 mA. The intrinsic bandwidth of these devices is estimated to be greater than 50 GHz. Nonlinear light-current characteristics of these lasers may lead to a high level of nonlinear harmonic distortion of the high-frequency output. They show that the relative intensity of the second harmonic response decreases rapidly at higher drive currents, in agreement with a phenomenological model based on the dc characteristics of the laser.
