We demonstrate the modeling and experimental results on the modulation bandwidth and frequency chirp of the transverse coupled cavity vertical-cavity surface-emitting lasers (TCC-VCSELs). Both a 3-dB-modulation bandwidth enhancement and chirp reduction are shown in the results. These improvements could be explained by an increase in differential net gain and photon-photon resonance introduced by strong coupling in coupled cavities. Our TCC VCSEL could be useful for higher data rates and longer link lengths of single-mode fiber transmissions.
