Abstract
This paper presents a review of recent research and development in high radiance LEDs intended for use as sources in optical fiber communications systems. Development in the last decade has resulted in reliable devices for use in the 0.8 to 0.9 μm wavelength region based on the AlxGai-xAs-GaAs double heterostructure material system. Both high-power and wide-bandwidth LEDs have been produced. Near-optimum performance of small area surface emitters (Burrus diodes) as well as edge emitters has been obtained. The paper will describe new trends in improving LED-to-fiber coupling efficiency, methods for reducing the nonlinearity of LEDs for analog applications, degradation mechanisms and device life. Recent achievement in long wavelength LEDs and PIN photodiodes has led to the development of a second generation of LED-fiber systems for operation at 1.3 μm wavelength, with data rates as high as a few hundred Mb/s and repeater spacings (or data link spans) of many kilometers.
