A 25-Gb/s direct modulation of an 850-nm implant-confined holey vertical-cavity surface-emitting laser (VCSEL) is demonstrated with a low operation current density of 7.4 KA/cm2 . The high-speed performance arises from cavity designs that are achieved using standard fabrication and epitaxial materials. The etched holey structure is incorporated into the top mirror of the VCSEL to tailor the size of...
25 Gb/s direct modulation and bit error measurements over 100m multimode fiber from an 850-nm implant-confined holey VCSEL are demonstrated. The high speed performance arises from cavity designs that are achieved using standard fabrication and epitaxial materials.
