Abstract :
Singlemode GaAs based vertical-cavity surface-emitting lasers (VCSELS) are being investigated for high bit rate data transmission in an industrially relevant temperature range between -20 and 100°C. The bit error rate (BER) for 2.5 Gbits/s transmission over 250 m of graded index multimode fibre (MMF) is better than 10-11 for all temperatures under fixed bias and modulation conditions. The temperature dependent power penalty for 250 m MMF transmission is as low as 0.009 dB/K
