Paper Abstract

Intrinsic and extrinsic limitations on conventional top-emitting high-speed VCSEL modulation bandwidth are discussed. A new VCSEL structure has been designed with reduced constraints on modulation bandwidth. The structure simultaneously addresses the primary extrinsic factors that limit the VCSEL modulation bandwidth. The new bottom-emitting, flip-chipped VCSEL structure improves heat-sinking, current injection uniformity, and reduces parasitic capacitance. We estimate the ultimate bandwidth of this new structure to be as high as 40Gb/s.
