1.5-1.6 μm VCSEL for metro WDM applications

摘要

The performance of an electrically pumped, continuously tunable,single-epitaxy VCSEL emitting in the 1530-1620 nm wavelength regime isreported. The VCSELs exhibit a continuous, repeatable andhysteresis-free wavelength-tuning characteristic. Further, the VCSELsare directly modulated at 2.5 Gbps and have >45 dB side modesuppression ratio (SMSR) over the entire tuning range. The performanceof such VCSELs make them highly promising for reconfigurable WDMmetropolitan area networks
