Abstract
A new dual-wavelength light-emitting diode (LED) emitting near 1.2 and 1.3 μm has been fabricated. The differential efficiencies of the two outputs were 0.36 and 0.88%, respectively. The intensities of these optical outputs can be controlled independently. The optical cross talk between the two wavelengths was −10 and −16 dB at 1.15 and 1.35 μm, respectively. This device is useful for wavelength-multiplexed optical communication systems.Keywords
