Abstract

InP-based buried tunnel junction vertical-cavity surface-emitting lasers (VCSELs) incorporating a novel short-cavity (SC) design are presented. These highly single-mode devices emitting at 1.55 μm show record-high modulation bandwidths in excess of 15 GHz together with greatly enhanced intrinsic resonance frequencies. For elevated temperatures of 65 °C and 80 °C, 3-dB-modulation bandwidths beyond 13 and 10 GHz are demonstrated, respectively. Reasons for the improved modulation behavior are the smaller intrinsic damping due to reduced photon-lifetime, and the better heat-management of these SC-VCSELs.
