Inhalt:
InP-based burried tunnel junction VCSELs incorporating a novel short-cavity design are presented. These devices show record-high modulation-bandwidths in excess of 15 GHz together with greatly enhanced intrinsic resonance-frequencies. Intrinsic damping is improved due to reduced photon-lifetime.
