Abstract
The small-signal frequency response of long-wavelength vertical-cavity lase rs (LW-VCLs) is of interest in determining the ultimate bandwidth of these devices for use in terrestrial networks. This letter analyzes two distinct device structures of double wafer-bonded vertical-cavity lasers operating a t 1.5 mum and compares their high-speed performance. We demonstrate the hig hest modulation bandwidth and the highest modulation current efficiency of an electrically pumped LW-VCL of 7 and 4.1 GHz/root mA, respectively.
