Abstract
We report the first vertical-cavity surface-emitting laser (VCSEL) tha t has been optimized for cryogenic applications near 77 K, with superi or characteristics that include a high-output power (P-out = 22 mW at I = 25 mA), high power conversion efficiency (eta(d) = 32%), low thres hold voltage (V-th = 1.75 V) and current (I-th = 1.7 mA), and low powe r dissipation (9 mW at P-out = 2.0 mW) for a 20-mu m-diameter device.
