Individually addressable monolithic 1 × 12 light-emitting diode array

Abstract

An optically and electrically interfaced array of twelve individually addressable surface emitting InP LED's aligned with a twelve-fiber-ribbon pigtail has been fabricated. The average coupled power per device into a 50-μm diameter core, graded index fiber at 150- mA drive current is 20 μW, with a FWHM spectral width at \lambda = 1.3 \mu m of less than 1450 Å. The p-contact diameter is 25 μm. Pulse rise and fall times in mesa-isolated devices are 4.5 and 5.5 ns, respectively.
