High-speed high-power 1.3-µm InGaAsP/InP surface-emitting LED's for short-haul wide-bandwidth optical-fiber communications

High-speed high-power double-heterostructure 1.3-µm InGaAsP/InP LED's have been developed for use in short-haul wide-bandwidth fiber-optics systems. At 150-mA dc, devices typically launch - 11.7 dBm into a 62-µm core graded index (GI) fiber. Optical bandwidth is typically 690 MHz with a 50-mA prebias. Modulation capability was demonstrated at 1-Gbit/s NRZ with - 15.7 dBm of peak power launched into the fiber. Rise and fall times of 340 and 780 ps, respectively, were achieved. Reliability data indicates a median life of ∼ 10
⁸
h for anticipated operating conditions.
