Abstract

The high-speed characteristics of a composite-resonator vertical-cavity laser (CRVCL) under both small- and large-signal electroabsorption modulation are investigated. The maximum -3dB modulation bandwidth of 12.5GHz is measured. The theoretical modulation response of the CRVCL is derived from the standard rate equations, and the qualitative form is in agreement with the measured results. The CRVCL under electroabsorption modulation exhibits a promising potential to extend the modulation bandwidth beyond that of a conventional VCSEL. However, the CRVCL under large-signal electroabsorption modulation is limited to low data rates, and the large relaxation oscillation resonance must be suppressed for higher-speed digital-optical link applications.
