A hetero-structure laser diode model


Additional modules to Harold

Harold XY Laser Module

The XY Laser Module allows you to perform 2D lateral-vertical (XY) simulations starting from a full physical description of the laser’s cross-section. The cross-section can include graded etching and insulating layers, and have n and p-contacts on the same side. This ideal for studying the effects of lateral structure in both ridge waveguide lasers and SOI hybrid lasers.

Harold EAM Module

Advanced physical model allowing to simulate electro-absorption modulators with Quantum-Confined Stark Effect (QCSE).
