A novel design for single and multi-aperture vertical-cavity surface-emitting lasers (VCSELs) is presented. It enables increased output power in concert with lower series and differential resistance and much improved thermal stability, combined with

Optimum photon lifetimes of vertical-cavity surface-emitting lasers (VCSELs) are shown to be target bit rate dependent. A comparison of the power budget in fJ/bit for optimized VCSELs operating at 25 Gb/s and 50 Gb/s is given. At 25 Gbit/s, the energ

Short distance optical communication in data centers has been dominated until now by multimode-fiber links based on multimode vertical cavity surface emitting lasers (VCSELs). Their large wall-plug and energy efficiency, as well as the relaxed requir

A low-cost method to adjust the mirror reflectivity of vertical-cavity surface-emitting lasers (VCSELs) helps to optimize the cavity photon lifetime. The joint variation of photon lifetime and the oxide aperture diameter of our 980-nm VCSELs allows o

We investigate experimentally the feasibility of single-mode VCSEL transmission at 910 nm over a graded-index single-mode fiber and achieve a BER < 10−12 for a transmission distance of 1-km at 25 Gb/s.
