Error-free 10 Gbit/s transmission using individual Fabry-Perot modes of low-noise quantum-dot laser

Abstract

A comb-generating laser suitable for DWDM application is demonstrated on the basis of a multimode quantum-dot laser. Bit error rate <10−13 at 10 Gbit/s external modulation was measured for 10 longitudinal modes owing to low (<0.3% over 0.001–10 GHz) relative intensity noise of each individual mode.
