Abstract

Chirp characteristics of a 1.55 μm vertical-cavity surface-emitting laser (VCSEL) were analyzed using a buried tunnel junction. The linewidth enhancement factor α_H was derived from the measurements. A high frequency modulation (FM) efficiency compared to edge emitters, was measured. It was shown that the carrier density modulation is flat over a broad frequency range (10 GHz/mW).
