Abstract
Record energy-efficient oxide-confined 850-nm single mode and quasi-single mode vertical-cavity surface-emitting lasers (VCSELs) for optical interconnects are presented. Error-free performance at 17 Gb/s is achieved with record-low dissipated power of only 69 fJ/bit. The total energy consumption is only 93 fJ/bit. Transmission lengths up to 1 km of multimode optical fiber were achieved. Our commercial quasi-single mode devices achieve error-free operation at 25 Gb/s across up to 303 m of multimode fiber. To date our VCSELs are the most energy-efficient directly modulated light-sources at any wavelength for data transmission across all distances up to 1 km of multimode optical fiber.
