Surface emitting l.e.d.s capable of simultaneous emission near 1.14 μm and 1.3 μm wavelengths, from an area 75 μm × 75 μm. have been fabricated and tested. Outputs of 0.5 mW and 0.8 mW, respectively, were obtained at the two wavelengths in initial devices driven at 50 mA d c. The measured crosstalk was −23.9 dB (electrical).
