Abstract :
The authors have demonstrated singlemode fibre optic transmission using double fused laterally oxidised InGaAsP vertical cavity QW lasers (VCLs) operating at 1.55 μm. Optimum performance was obtained with VCLs with an oxidised aperture of 6-7 μm. These VCLs had a maximum sidemode suppression ratio of 47 dB under pseudorandom modulation, a maximum bandwidth of 4.6 GHz and a current modulation efficiency factor of 3.3 GHz/√[mA]. A bit error rate <10-9 was achieved for transmission over 200 km at 622 Mbit/s
