Optimized Modulation Bandwidth and Henry Factor of Fabry-Perot InAs/InP Quantum Dash Based Ridge Waveguide Lasers for Access/Metro Networks
01 January 2014
Unprecedented high modal gain of ~100 cm-1 is obtained for an optimized structure based on InAs/InP quantum dashes (QDash) emitting at 1.55 μm. This structure allows achieving ~10 GHz direct modulation bandwidth. P-type doping reduces the Henry factor value down to 2.7.
