Abstract

In this work, we perform a multi-parameter design study to improve the performance of an uncooled directly modulated 1.3 μm GaInNAs ridge waveguide laser for high speed operation especially at high temperature. The static and dynamic performance of the improved design is analyzed using an accurate in-house 2D electro-opto-thermal laser simulator. The improved structure is shown to have a lower threshold current, higher thermal roll-over limit and higher modulation bandwidth—especially under high temperature operation. The improved structure also has a lower vertical beam divergence compared to a reference structure with a conventional design.
