Frequency response of an InGaAsP vapor phase regrown buried heterostructure laser with 18 GHz bandwidth

Abstract
The frequency response of a 1.3-μm InGaAsP vapor phase regrown buried heterostructure laser with an 18-GHz cw bandwidth is analyzed in detail. The intrinsic bandwidth of the device is shown to be 22 GHz and the 3-dB RC roll-off frequency due to electrical parasitics is found to be 10 GHz.
