Bias-free 1 Gbit/s data transmission using singlemode GaAs VCSELs at /spl lambda/=835 nm

摘要

Bias-free 1 Gbit/s pseudo-random data transmission using a laterally oxidised singlemode GaAs vertical-cavity surface-emitting laser is demonstrated and compared to biased modulation. A bit error-rate of 10/sup -11/ obtained -28 dBm received optical power makes these laser devices very attractive for optical interconnection.
