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 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\lambda = 1.3 \mu</tex> 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.
