Abstract :
Optical preamplification at 10 Gbit/s using a vertical-cavity semiconductor optical amplifier (VCSOA) is demonstrated. The VCSOA has a narrow gain bandwidth of 37 GHz and consequently functions as an amplifying filter. At a fibre-to-fibre gain of I I dB, the receiver sensitivity was increased by 7 dB resulting in a sensitivity of -26.2 dBm
