title = "2.6 K VCSEL data link for cryogenic computing",
abstract = "Cryogenic computing requires an energy-efficient optical data link from 4 K to the end-user at room temperature. Laser spectra and light-current-voltage family curves over a wide temperature range from 2.6 to 295 K are reported on oxide-vertical cavity surface emitting lasers coupled with OM4 fiber. Non-linear shifting of the lasing wavelength vs junction temperatures is measured with the wavelength shifting coefficients <0.005 nm/K at 2.6 K. 12.5 Gb/s non-return-to-zero error-free data transmission at 2.6 K to the error detector at 295 K is demonstrated as a viable solution for cryo-computing.",
