High-power single-mode optical-fibre coupling to LEDs has been achieved by novel mesa-structure InGaAsP 1.3 μm surface-emitting LEDs. A −26.7 dBm (2.1 μW) fibre-coupled power has been obtained with 210 MHz optical −3 dB modulation bandwidth at 23°C 50 mA current. The 140 Mbit/s transmission feasibility over a single-mode optical fibre has been studied.
