Abstract :
The intensity noise spectrum is measured for antimonide based 1.3 μm vertical-cavity surface emitting lasers. Analysis of the noise spectra indicates a modulation bandwidth of 5.7 GHz with an intrinsic maximum frequency response that exceeds 28 GHz. A discontinuity in the relaxation oscillation resonance frequency is observed, which suggests that the lasing behavior at threshold is assisted by nonlinearities in the gain medium.
