摘要：

Visible (660 nm) resonant-cavity light-emitting diodes (RCLED's) have been fabricated. The top-emitting, planar devices employed two AlGaAs-AlAs-Bragg mirrors and GaInP-AlGaInP quantum-well active layers. The device performance was characterized as ai function of the device diameters, ranging from 24 to 202 mu m. The larger devices exhibited a nearly linear increase of output power with injected current with 8,4-mW emission at 120 mA, A maximum external efficiency of 4.8% was measured at 4 mA on the 84-mu m aperture devices. All devices exhibited a narrow emission at 659-661 nm with a linewidth around 3 nm, The results show that RCLED's are promising low-cost light sources for plastic fiber transmission as well as display applications.
