Abstract
InGaAsP 1.3-μm LEDs are reliable inexpensive alternatives to laser diodes in intermediate range optical communication systems such as local area networks and subscriber loops. High-power LEDs with a high modulation bandwidth are very attractive sources for these systems. However, it has been very difficult to achieve these two performances simultaneously because of power-bandwidth trade-offs.1,2 The highest reported power launched into 50-μm core 0.20-N.A. graded-index (Gl) fiber was 50-80 μW with a 50-100-MHz modulation bandwidth.1
