Abstract

The highest bit rate transmitted to date using VCSELs has been achieved when operating the devices in the transverse single-mode linearly polarized regime. On the other hand it has been shown at 500 Mbit/s that transverse multi-mode InGaAs VCSELs are less sensitive to mode selective loss (MSL) due to their low coherence. In this contribution we study the effect of MSL in graded index multi-mode fiber of 50 /spl mu/m core diameter at 2.5 Gbit/s data rates. We investigate both, transverse single-mode and transverse multi-mode VCSEL transmitters.
