Static and dynamic performance optimization of a 1.3 µm GaInNAs ridge waveguide laser
Paper in proceeding, 2008

In this work, we optimise the structure of an uncooled directly modulated 1.3 μm GaInNAs ridge waveguide laser for high temperature operation. The static and dynamic performance of the optimised design is analyzed using an accurate in-house 2D electro-opto-thermal laser simulator. The optimised structure Is shown to have a lower threshold current, higher efficiency, higher modulation bandwidth and lower vertical beam divergence compared to a reference structure with a conventional design. Large-signal 10 Gbit/s digital modulation simulations were performed and demonstrate the improved performance of the optimised structure especially under high temperature operation.
